The government has a balanced budget.(a) Illustrate the economy of Country X on a fully labeled production possibilities curve, assuming increasing opportunity cost. Label a point where the economy is currently operating as point X.(b) The government of Country X reduces the tax rates for interest earned on household savings. Would the national savings decrease, increase, or stay the same? Explain.(c) On a fully labeled loanable funds market graph, illustrate the impact of the policy from part (b) on the equilibrium real interest rate and the equilibrium quantity of funds.(d) Assume that Country X is still maximizing resource use. On your PPC graph from part (a), illustrate the short-run impact of the change in real interest rates. Illustrate a new production point as point R.(e) In the long run, will the long-run aggregate supply of Country X decrease, increase, or stay the same? Explain.
In an effort to increase sales, a company is considering a new training program for its sales department. An advertisement claims that the training program leads to a mean increase of $5000 in monthly sales. To study the program's effectiveness, the company selects 20 sales representatives, randomly assigning 10 to the training program and 10 to serve as control. On average, the representatives who participated in the training brought in $8231 more in monthly sales than the control, and the 95% confidence interval for the difference in means was (2799, 13663) dollars. Does this confidence interval provide convincing statistical evidence that the mean increase in sales is different from the advertised value?A) No, because $0 is outside the interval the results are not statistically significant.B) No, because $5000 is included in the interval the results not statistically significant.C) Yes, because $0 is outside the interval the results are statistically significant. D) Yes, because the representatives were randomly assigned and $8231 is different from $5000.E) Yes, because $8231 is inside the confidence interval the results are accurate.
