• Write a program that asks the user for a number in the range of 1 through 7. The program should display the corresponding day of the week, where 1 = Monday, 2 = Tuesday and so forth. If the user types in a 6 then "Saturday" should be printed on the screen.
• The program should display an error message if the user enters a number that is outside the range of 1 through 7.
• Name the source code file
• Test and run the program. Capture the output console and save it as an image file

The medium-run equilibrium is characterized by four conditions:

- Output is equal to potential output (Y=Y_n)

- The unemployment rate is equal to the natural unemployment rate (u=u_n)

- The real policy interest rate is equal to the "natural" rate of interest (the one that makes aggregate demand equal to potential output).

- The expected rate of inflation is equal to the actual rate of inflation.

(a) Assume that the level of expected inflation is formed in such a way that this year's expected inflation is equal to last year's inflation: πe=πt−1πe=πt−1. What is the behavior of the rate of inflation in a medium-run equilibrium?

Select one:

a. it will not change, meaning that the price level remains constant year after year.

b. it will be constant and equal to an exogenous constant, that does not depend on past inflation.

c. it will be increasing or decreasing depending on the value of the natural interest rate.

d. it will not change: the value of inflation is simply equal to its value in the previous period.

(b) Now assume, instead, that the level of expected inflation is equal to an exogenous constant:

πe=π¯πe=π¯

What is the behavior of actual inflation in the medium-run equilibrium?

Select one:

a. it is increasing or decreasing, depending on the value of the "natural" rate of interest

b. It is constant, and equal to its previous period.

c. It is stable and equal to the exogenous constant π¯π¯

d. inflation is increasing at a rate equal to π¯

(c) Imagine that the economy is in a medium-run equilibrium. Assume that expected inflation is equal to past inflation (πe=πt−1πe=πt−1).

In this situation, the Government decides to increase public spending (G), while leaving taxes unchanged. How will macroeconomic variables react to this fiscal expansion?

Select one:

a. output will increase; the unemployment rate and nominal wages will remain the same (equal to the values determined by the WS-PS model); the inflation rate will start increasing year after year.

b. output will decrease; the unemployment rate and nominal wages will remain the same (equal to the values determined by the WS-PS model); the inflation rate will start decreasing year after year.

c. output will increase; the unemployment rate will decrease; nominal wages will remain the same; the inflation rate will start increasing year after year.

d. output will increase; the unemployment rate will decrease; the growth rate of nominal wages and the inflation rate will start increasing year after year.

(d) How must the Central Bank react to the increase in G, in order to ensure that the economy sticks to the medium-run equilibrium?

Select one:

a. it must increase the interest rate.

b. it must decrease the interest rate.

c. it must ensure that the interest rate remains unchanged.

d. it must do nothing: output is already equal to potential output.

e. it must increase taxes.

A union leader in the Maritime Workers' Union believed that workers at the Port of Brisbane were receiving a lower weekly salary than workers at Port Kembla. To determine whether this claim was valid, they took samples of size 17 and 11 in Brisbane and Port Kembla, respectively, and found that the average and standard deviation of the weekly salaries were $914.11 and $49.38 respectively in Port Kembla, and $859.23 and $55.62 in Brisbane. Use Brisbane minus Port Kembla, and answer correct to two decimal places. 1. Determine a point estimate for the difference in the average weekly salary between the two ports. ? 2. Calculate the standard error for the difference between sample means assuming that the workers' salaries in both locations are normally distributed and have the same population variance. ? 3. Use Kaddstat to determine a 95% confidence interval for the difference between the mean weekly salaries in Brisbane and Port Kembla. lower limit ? upper limit ?

A piston contains 600 moles of an ideal monatomic gas that initally has a pressure of 2.44 × 105 Pa and a volume of 1.8 m3. The piston is connected to a hot and cold reservoir and the gas goes through the following quasi-static cycle accepting energy from the hot reservoir and exhausting energy into the cold reservoir. The pressure of the gas is increased to 5.44 × 105 Pa while maintaining a constant volume. The volume of the gas is increased to 8.8 m3 while maintaining a constant pressure. The pressure of the gas is decreased to 2.44 × 105 Pa while maintaining a constant volume. The volume of the gas is decreased to 1.8 m3 while maintaining a constant pressure. It may help you to recall that CV C V = 12.47 J/K/mole and CP C P = 20.79 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas. 1) How much energy is transferred into the gas from the hot reservoir? J 2) How much energy is transferred out of the gas into the cold reservoir? J 3) How much work is done by the gas? J 4) What is the efficiency of this cycle?
