Survey of Workers In a survey of 703 randomly selected workers, 15.93% got their jobs through newspaper ads (based on data from Taylor Nelson Sofres Intereach). Consider a hypothesis test that uses a 0.05 significance level to test the claim that less than 20% of the workers get their jobs through newspaper ads.
a. What is the test statistics?
b. What is the critical value?
c. What is the P-value?
d. What is the conclusion?
e. Based on the polling results, can we conclude that 15.93% is significantly less than 20% for all such hypothesis tests? Why or why not?
Hypothesis testing for survey workers at Sofres Intereach are examines. The test statistic, critical value, P-value and conclusion is given.
