Answer the following questions with clear explanation.

a. Explain intuitively what does population mean and variance tells you about the distribution of a random variable?

b. Can you think of a reason why do we mostly only care about mean and variance a random variable since the distribution function could involve more than the two parameters?

c. Explain why we could use a sample data to draw conclusions about a population parameter?

d. Is p-value of a hypothesis test a random variable, why? e. If you reject your null hypothesis, you have proved that the null hypothesis is wrong. Is this a correct statement, why?

Answer each of the following questions. Use a graphical explanation if it is stated and explain each step of your answer. Answers without an explanation will lose points. a) (4 pts) Suppose the government executes an expansionary fiscal policy. By using the AS-AD graph explain under which conditions an expansionary fiscal policy works well and under which conditions it does not work well. Explain each step in your answer. b) (3 pts) Explain the crowding-out-of-investment of a decrease in the...

1. Which of these are random variables: Population mean, sample mean, population variance, sample variance, population standard deviation, sample standard deviation, population range, sample range 2. Does variance matter? I have two routes to my work. Travel time on the first route takes me on average 20 minutes, and the second route 19 minutes. The standard deviation of travel time on the first route is 1.5 minutes, on the second is 5 minutes. Which route should I take?

What does the population mean for your population (that is the value population mean)? What is the mean of your sampling distribution of sample means (that is the value sampdistrmean)? According to the Central Limit Theorem, there is a formula relating the population means and the mean of the sampling distribution of sample means. What is that formula and how well did the outcomes of your simulation match that formula? Explain and specifically reference the formula.

Answer the following questions either true, false, explain your answer. The explanation is the most important part of your answer. An increase in the money supply will shift the AD curve upwards and to the right. The larger the MPC, the smaller the Keynesian government spending multiplier. Contractionary monetary policy shifts the AD curve to the right. Structural unemployment is caused by fluctuations in economic activity. Nominal GDP can be equal to real GDP. If the reserve ratio 0.1, the...
