According to a simple random sample of 3026 civilian American workers, 18.1% of them have a minimum educational level of a bachelor's degree. (a) A news article claims that fewer than 20% of all civilian American workers possesses a bachelor's degree. Conduct a hypothesis test to determine if these data provide strong evidence supporting this statement. The hypotheses for this test are: Ho: p= .2 HA: P < .2 Ho: p= .2 HA: P > .2 Ho: p= .2 HA: P = .2 The test statistic is: (please write at least four decimal places) The p-value (please write at least four decimal places) associated with this hypothesis test is: What is the conclusion of the hypothesis test? Since p≥ a we reject the null hypothesis and accept the alternative Since p

According to a simple random sample of 3026 civilian American workers, 18.1% of them have a minimum educational level of a bachelor's degree. (a) A news article claims that fewer than 20% of all civilian American workers possesses a bachelor's degree. Conduct a hypothesis test to determine if these data provide strong evidence supporting this statement. The hypotheses for this test are: Ho: p= .2 HA: P < .2 Ho: p= .2 HA: P > .2 Ho: p= .2 HA: P * .2 The test statistic is: (please write at least four decimal places) The p-value (please write at least four decimal places) associated with this hypothesis test is: What is the conclusion of the hypothesis test? Since p≥ a we reject the null hypothesis and accept the alternative Since p<a we reject the null hypothesis and accept the alternative Since p<a we fail to reject the null hypothesis Since p ≥ a we accept the null hypothesis Since p ≥ a we do not have enough evidence to reject the null hypothesis Interpret the result of the test in the context of this study and article: The data do not provide sufficient evidence to claim that less than 20% of American civilian workers have a bachelor's degree The data provide sufficient evidence to claim that less than 20% of American civilian workers have a bachelor's degree (b) Would you expect a 95% confidence interval for the proportion of American civilian workers who possess a bachelor's degree to include 0.2? no yes
