John, an experienced Airbnb host claims that true average rental price per night for a shared room in lower east side of Manhattan is $100. A sample of 15 shared room rentals from the neighborhood yields a sample average price per night of $85 with a standard deviation $17 (source: Kaggle.com). Suppose the distribution of price per night is normally distributed. Is there sufficient evidence to believe that average price per night for a shared room in Manhattan's lower east side is less than what John claims? (Use 5% significance level)? 1. (4 points) Clearly state the null and alternative hypothesis to answer the above research question. Define any parameters you may use. 2. (2 points) Check the conditions that needs to be satisfied in order to do the test you stated in part 1.

d) Assume that at a pre-depreciation of the rand against the U.S. dollar, South Africa (S.A.) exports 500 units to and imports 700 units from the U.S. (You do not need to know the actual prices of imports and exports, but assume that the trade or current account is initially balanced.) Suppose now there is a 15% appreciation of the U.S. dollar against the rand and that because of the domestic currency depreciation, exports rise to 550 units and imports fall to 630 units. [Assume that the prices of imported goods are denominated in foreign currency and the prices of exported goods are denominated in domestic currency.] (i) Calculate the home-country price elasticity of demand for imports. [Show formula and round off your solution to a maximum of TWO decimal places.] [4] (ii) Calculate the percentage depreciation of the domestic currency against the foreign currency. [Show formula - you need not derive the formula - and round off your solution to a maximum of TWO decimal places.] [4] (iii) Now using the export volume statistics, and your solution in (ii) above, calculate the price elasticity of demand for home-country exports. [5] (iv) Would the simple Marshall-Lerner condition suggest that South Africa's trade (or current account) balance has improved or deteriorated because of this depreciation of its currency? Why? [Your answer should include the calculations and round off your solution to TWO decimal places.] [3]

Can someone please tell me how to code this? I'm new to Java. import java.util.Scanner; public class Multiply { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print("Enter the first number: "); int a = sc.nextInt(); System.out.print("Enter the second number: "); int b = sc.nextInt(); int c = 0; // Add your code here. System.out.println(c); } } Changing values 1: You have some code which declares two variables and initializes them from user input. The code then declares a third variable and prints it out. When you run it, it will wait for you to enter the two numbers. When you mark it, it will compare the results of your code to a small number of test cases. Note that Your task is to change the value of the third variable to the product of the first two variables. Hints: - You need to multiply the values of variables a and b and assign the result to variable c.
