CI and Hypothesis Testing Examples 1. A recent survey of the starting salaries for new Ph.D. economists reported a sample mean starting salary of: $ \bar{X} = \$120,000 $ with a sample standard deviation of: $ S = 18,000 $. For a sample size $ n = 25 $, construct a 90% confidence interval $ (\alpha = 10\%) $ for the population mean $ \mu $. Show the Margin of Error (ME) the Lower Confidence Limit (LCL) and Upper Confidence Limit (UCL).

(Polynomial interpolation, 10pts) Consider the following three samples of some function f(x): \begin{tabular}{c|c} $x$ & $f(x)$ \ hline -1/2 & -1 \ 1 & 2 \ 3 & -1/4 \end{tabular} (a) Determine the unique second degree polynomial interpolant $p_2(x)$ to the above data using Lagrange's interpolation formula. You do not need to simplify the result. You may either work this out by hand or simply write an anonymous function in for the polynomial. (b) Repeat part (a) but use the Vandermonde matrix approach. In this case you will be solving for the coefficients $a_0$, $a_1$, and $a_2$ in the polynomial $p_2(x) = a_0 + a_1x + a_2x^2$ that interpolates the data. You can simply set up the linear system and solve the linear system in MATLAB. Be sure to print out the coefficients. (c) Show that (a) and (b) give the same result. You can do this by numerically comparing the polynomials at several (i.e. 100) points over the interval [-1,1].

2. In this part of the assignment, you are required to create a separate C# Console Application project. The project name should be A3< first and last Name initials of everyone in your group>>P2. For example, a student with team members John Smith, Bill Anderson would name their project A3JSBAP2. Write a C# (console) program to create an interface that acts as a simple four number calculator. Your program should continue doing calculations until it is closed or exited. Instead of a Graphical User Interface (GUI) keypad, this calculator will use console input to accept the four numbers to be used in the calculation. This calculator needs to prompt the user for ONE selection of any of these simple math operators: plus, multiply, minus or divide. Five (5) inputs will need to be prompted: 1. Selected mathematical operation, (1-Add, 2-Multiply, 3-Subtract, 4-Divide) 2. Allow the user to enter 1,2,3,4 number. 3. Enter numbers that the User has said they were going to Enter, Example: Menu: Conestoga's PROG1925 Calculator 1. Add 2. Subtract 3. Multiply 4. Divide User choses 1. How Many numbers do you wish to Calculate? Users Enter's 4....... The program would add all numbers Therefore... The output will be displayed when the mathematical operation is known, and the inputs (numbers) are entered. • If the user selects addition (plus) add all numbers together. • If the user selects subtraction only subtract(minus) each number as entered. • If the user selects division (divide) allow only 2 numbers to be entered. • If the user selects multiplication (multiply), multiply each number as entered. The output will not be editable by the user. After the calculation is executed, the application will display error messages (or other status message) and can be as you deem appropriate. • The program only needs to run once then exit • This calculator will handle all errors using try/catch statements. The error message output should display at least 3 different types of error (or status) messages, depending on what the user has done incorrectly. Your program should be able to catch all possible errors the user may do; it should not crash.
