Suppose a government bans flavored vaping products and wishes to know if this decreases the proportion of teenagers who vape at least once each month, which was known to be 16%. A survey after the ban on flavored vaping products finds that out of the 200 teenagers surveyed, 26 had vaped at least once in the previous month. Assuming no other factors influenced the survey replies, did the ban on flavored vaping products reduce the proportion of teenagers who vape at least once in a month? Use a significance level of 0.05.

(a) What are the null and alternative hypotheses?

(b) What is the test statistic?

(c) What is the critical value?

(d) Do you reject or fail to reject the null hypothesis? Explain your reasoning.

(e) Can you conclude that the ban on flavored vaping products reduced the proportion of teenagers who vaped at least once a month?

Suppose a government official wants to know what proportion of residents are infected with the an illness. There are a limited number of tests. So a random sample of 180 residents was taken, and these residents were tested for the illness. Of these 180 people, 36 were found to be infected with the illness. a) Find a 95% confidence interval for the true proportion of residents who are infected. b) a healthcare professional says they suspect that fewer than 30%...

Suppose a government official in Phoenix, Arizona, wants to know what proportion of Phoenix residents are infected with the COVID-19 virus. Because of the limited availability of tests, she cannot test all the residents of Phoenix. A random sample of 180 Phoenix residents was taken, and these residents were tested for the virus. Of these 180 people, 36 were found to be infected with the virus. Find a 95% confidence interval for the true proportion of Phoenix residents who are...

A college wishes to know the proportion of American adults who are bilingual. The survey includes asking 280 randomly selected American adults and finds that 123 are bilingual. Find the point estimate of the percentage of adults who speak two or more languages. Find a 99% confidence interval estimate of the percentage of Americans who are bilingual? Are the majority of Americans bilingual? Explain.

Suppose an economy is Initially in equilibrium at potential GDP, Y*. Then the government decreases the net tax rate (t). Briefly explain in words (1-2 sentences without a diagram) What type of gap would be caused by this policy AND the impact on real GDP and the price level in the short-run. Decreased net tax rate cause an overall decrease in real GDP, Briefly explain in words (1-2 sentences with no diagram) how the economy adjusts back to the long...

Suppose we wanted to know if there is a difference in the proportion of citizens from different provinces who would support the idea of federal laws for mask wearing in public. Upon collecting some sample data we find that 34 out of 50 residents of Ontario would support such legislation, while only 28 out of 50 residents of Alberta support the idea of such laws. a.) Conduct the appropriate test of hypothesis for these data at the .05 level b.)...

Question 3: Suppose federal government decreases taxes by (ΔT= 10 million) and increases government spending by (ΔG = 20 million), as a result output is changed by (ΔY). a. (10 points) Assuming that the Federal reserve changes money supply such that the interest rate stays constant and marginal propensity to consume is MPC= 0.6. What is the change in output (ΔY)? What is ΔY ? What is ΔY? Show your work. ΔT ΔG b. (10 points) If the fed does...

Suppose the Phillips curve is correct. If the government increases taxes, then aggregate demand decreases and unemployment falls in the short run Select one: True False According to the long-run Phillips curve, in the long run, unemployment depends upon factors such as fiscal and monetary policies that are designed to reduce cyclical unemployment. Select one: True False Proponents of rational expectations argued that if people expected a decrease in the money supply growth rate and inflation, then the decrease in...

Suppose you’re hired by the government of Spain to estimate the proportion of residents who are atheists. According to the guidelines, the estimate must have a margin of error no greater than 1% with 95% confidence. How many people would you have to sample to ensure that you are within the guidelines? Show a calculation to support your answer.
