A newspaper is considering the launch of an online edition. The newspaper plans to go ahead only if it's convinced that more than 35% of current readers would subscribe. The newspaper contacts a simple random sample of current subscribers, and decided that based on this study, not go ahead with the launching of the online edition. They based this decision based on a test using a=0.05

Hint:while the p-value is not given, there is enough information in the problem to determine if it is more or less than the stated alpha of 0.05

12) Would they have made the same decision at a= 0.011? Explain

13) Would they have made the same decision at a=0.10? Explain

In April of 2019, the unemployment rate in Canada was reported to be 7.6%. Suppose you wish to conduct a test to determine if the current unemployment rate differs from that of April 2019, at the 5% significance level. You take a random sample of 1000 Canadians and found 91 of them to be unemployed.

The assumptions have been checked (and are all met). You need to calculate the test statistic and p-value, but you may use software if you wish

14) State the null and alternative hypothesis in symbols only.

Select one:

a: Ho:p=0.076, Ha: p 0.076

b. Ho:p=0.091, Ha:p 0.091

c. Ho:p=0.076, Ha: p>0.076

d. Ho:p=0.091, Ha:p>0.091

15) What is the value of the test statistics?

a. 1.65

b.-1.65

c. 1.79

d. -1.79

16) What is the value of the P-value?

a. 0.0367

b. 0.0734

c. 0.9633

d. 1.9266

17) Since the assumptions are met, which of the following is the correct conclusion?

a. at the 5% significance level we can conclude that the unemployment rate in Canada is different than the 2019 rate of 7.6% for the population of all Canadians

b. At the 5% significance level we cannot conclude that the unemployment rate in Canada is different that the 2019 rate of 7.6% for the population of all Canadians

c. At the 5% significance level there is no evidence that the unemployment rate in Canada is different than the 2019 rate of 7.6%, for the population of Canadians

d. At the 5% significance level we can conclude that the unemployment rate in Canada is the same as the 2019 rate of 7.6% for the population of all Canadians
