The table below shows data on the returns over five 1-year periods for seven mutual funds. A firm's portfolio managers will assume that one of these scenarios will accurately reflect the investing climate over the next 12 months. The probabilities of each of the scenarios occurring are 0.1, 0.3, 0.1, 0.1, and 0.4 for years 1 to 5, respectively. RETURNS OVER FIVE 1-YEAR PERIODS FOR SEVEN MUTUAL FUNDS Planning Scenarios for Next 12 Months Mutual Funds Year 1 Year 2 Year 3 Year 4 Year 5 Large-Cap Stock 35.3 20.0 28.3 10.4 -9.3 Mid-Cap Stock 32.3 23.2 -0.9 49.3 -22.8 Small-Cap Stock 20.8 22.5 6.0 33.3 6.1 Energy/Resources Sector 25.3 33.9 -20.5 20.9 -2.5 Health sector 49.1 5.5 29.7 77.7 -24.9 Technology Sector 46.2 21.7 45.7 93.1 -20.1 Real Estate Sector 20.5 44.0 -21.1 2.6 5.1 Develop a portfolio model for investors who are willing to risk a portfolio with a return no lower than 2%. Round your answers to one decimal place. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. If the constant is "1" it must be entered in the box. To determine the percentage of the portfolio that will be invested in each of the mutual funds we use the following decision variables: LS = proportion of portfolio invested in a large-cap stock mutual fund MS = proportion of portfolio invested in a mid-cap stock fund SS = proportion of portfolio invested in a small-cap growth fund ES = proportion of portfolio invested in an energy sector fund HS = proportion of portfolio invested in a health sector fund TS = proportion of portfolio invested in a technology sector fund RS = proportion of portfolio invested in a real estate sector fund Max s.t. LS + MS + SS + ES + HS + TS + RS ≥ 0.02 LS + MS + SS + ES + HS + TS + RS = 1 LS, MS, SS, ES, HS, TS, RS ≥ 0 Solve the model in part (a) and recommend a portfolio allocation for the investor with this risk tolerance. Round portfolio return to three decimal places and other answers to one decimal place. If your answer is zero, enter "0". The recommended allocation is to invest as follows: __% of the portfolio in the large-cap stock mutual fund __% of the portfolio in the mid-cap stock fund __% of the portfolio in the small-cap stock fund __% of the portfolio in the energy sector fund __% of the portfolio in the health sector fund __% of the portfolio in the technology sector fund __% of the portfolio in the real estate sector fund The expected portfolio return is ______% Modify the portfolio model in part (a) and solve it to develop a portfolio for an investor with a risk tolerance of 0%. Round portfolio return to three decimal places and other answers to one decimal place. If your answer is zero, enter "0". The recommended allocation is to invest as follows: __% of the portfolio in the large-cap stock mutual fund __% of the portfolio in the mid-cap stock fund __% of the portfolio in the small-cap stock fund __% of the portfolio in the energy sector fund __% of the portfolio in the health sector fund __% of the portfolio in the technology sector fund __% of the portfolio in the real estate sector fund The expected portfolio return is _______ %.

Need help with a JAVA program especially the GUI part as its formatting is something I cannot figure out. According to the Inheritance and encapsulation principles, you have to design and implement a super-class Product and the subclasses Electronics and Clothing. Also, you will have to add at least one constructor for each class. The class Product should be abstract and include appropriate get/set methods and hold information about the product ID (mix of characters and numbers), product name, number of available items, and the price. (You can add any other information that you consider appropriate). In particular: • The Electronics subclass should hold specific information and methods. You should add the brand and the warranty period as instance variables, constructors, and the relative get/set methods. • The Clothing subclass should hold specific information and methods. You should add the size and color as instance variables (attribute), constructors, and the relative get/set methods. • You should implement a class ShoppingCart to represent the user’s cart. The class should contain a list of products as instance variable, there should be methods to add, remove and calculate the total cost. • Design and implement a class called RAMShoppingManager, which implements the interface ShoppingManager. RAMShoppingManager maintains the list of the products in the system and provides all the methods for the system manager defined in the console menu. Console Menu Implementation (Phase 2) The class RAMShoppingManager should display a menu in the console (not in the GUI) containing the following management actions from which the manager can select one. – You should have a menu with a list of options • Add a new product to the system. It should be possible to add either electronics or clothing, with all the relevant information (all the attributes defined in the relative class). You should consider that the system can have a maximum of 50 products. • Delete a product from the system, inserting the product ID. Display a message with the information of the product (if it is electronics or clothing) that has been deleted and the total number of products left in the system. • Print the list of the products in the system. For each product, print on the screen all the information (attributes defined in the corresponding class) and say if it is electronics or clothing. The list should be ordered alphabetically according to the product ID. • Save in a file the list of products that have been added to the system, with all the relative attributes. The next time the application starts, it should be able to read back all the information saved in the file and continue to use the system. Graphical User Interface (GUI) Implementation (Phase 3) While the manager interacts with the system through the menu console, the client will interact with the system through a graphical user interface. Open a Graphical User Interface (GUI) from the menu console – you will have an additional option that the user can select to open the GUI. You should implement the GUI according to the following requests: • The user can select from a drop-down menu which type of product can be visualized (all, Electronics, or Clothes). • The user can visualize the list of products with relative information as displayed below. The user should be able to sort the list alphabetically. You should use a table to display this information on the GUI. • The user can select a product and add it to a Shopping Cart. When implementing these functionalities, you need to comply with the following requirements: o the items with reduced availability (less than 3 items available) should be in red on the table. o When the user selects the product, the product details (all the information related to the product) should appear in a panel below the table. o the user can add the item to the shopping cart by clicking the relative button. The user can visualize the shopping cart by clicking the ‐Shopping Cart‐ button. The user can select another item and keep adding items to the shopping cart. o the shopping cart will show the list of products and the final price. To calculate the final price, the system will apply the following discounts: • 20% discount when the user buys at least three products of the same category. • If the discount is applied, the message will appear on the GUI showing the final cost.

mutual-funds-are-classified-as-load-or-no-load-funds-load-funds-require-an-investor-to-pay-an-init-2

Mutual funds are classified as load or no-load funds. Load funds require an investor to pay an initial fee based on a percentage of the amount invested in the fund. The no-load funds do not require this initial fee. Some financial advisors argue that the load mutual funds may be worth the extra fee because these funds provide a higher mean rate of return than the no-load mutual funds. A sample of 30 load mutual funds and a sample of 30 no-load mutual funds were selected. Data were collected on the annual return for the funds over a five-year period. The data are contained in the data set Mutual. The data for the first five load and first five no-load mutual funds are as follows. $$\begin{array}{lllc} \text { Mutual Funds-Load } & \text { Return } & \text { Mutual Funds - No Load } & \text { Return } \\ \text { American National Growth } & 15.51 & \text { Amana Income Fund } & 13.24 \\ \text { Arch Small Cap Equity } & 14.57 & \text { Berger One Hundred } & 12.13 \\ \text { Bartlett Cap Basic } & 17.73 & \text { Columbia International Stock } & 12.17 \\ \text { Calvert World International } & 10.31 & \text { Dodge \& Cox Balanced } & 16.06 \\ \text { Colonial Fund A } & 16.23 & \text { Evergreen Fund } & 17.61 \end{array}$$ a. Formulate $H_{0}$ and $H_{\mathrm{a}}$ such that rejection of $H_{0}$ leads to the conclusion that the load mutual funds have a higher mean annual return over the five-year period. b. Use the 60 mutual funds in the data set Mutual to conduct the hypothesis test. What is the $p$ -value? At $\alpha=.05,$ what is your conclusion?

00:01 So the solution of the problem is we have been given.

00:05 First step one, we have to decide decision variables.

00:25 So it is like x -14, large -cap, stock, chelfand, x2 is mid -cap, x -3 is small -cap, x -4 -h, energy sector, x -5 -h, l -sector, f6 is technology sector, f7 is real estate.

01:45 So in a step to formulate objective function, so we write maximize 9 .68 x1 plus 5 .91 x2 plus 15 .20 x3 plus 11 7 .74 x4 7 .34 x5 plus 16 .97 x6 plus 15 .4 x7.

03:05 In the next step, three, set up constraints, for example, 35 .3 x1 plus 32 .3x2 plus 20 .8 x3.

03:34 Plus 25 .3 x4 plus 49 .1 x5 .46 .2x6 plus 20 .5 x7 is greater than equal to.

04:00 Similarly, we can write other constraints.

04:04 So we get results in a sum of table.

04:13 So parameters we get the result is ls 0 .000000.

04:24 Ms 0 .00 s s sum of square 0 .500...
