Hypothesis Testing with a Sample Mean Previously, an organization reported that teenagers spend 4.5 hours per week, on average, on the phone. The organization thinks that, currently, the mean is higher. Fifteen randomly chosen teenagers were asked how many hours per week they spend on the phone. The sample mean was 4.75 hours with a sample standard deviation of 2.0. Conduct a hypothesis test. The null and alternative hypotheses are: O Ho: p = 4.5 H.u > 4.5 O Ho: u 2 4.5 H p 4.75 O Ho:p = 4.5 H p > 4.5
please help solve below questions pertaining to attached image find the test statisitic find the p value State the conclusion for the test. A. Reject the null hypothesis. There is sufficient evidence to support the claim that archbishops have lower mean longevity than monarchs. B. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that archbishops have lower mean longevity than monarchs. C. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that archbishops have lower mean longevity than monarchs. D. Reject the null hypothesis. There is not sufficient evidence to support the claim that archbishops have lower mean longevity than monarchs.

Directions: Answer the following. 1. What are the steps in testing hypothesis for the population mean? 2. In a right-tailed test, what will you da if the computed value is greater than the critical value? 3. In a left-tailed test, what will you do if the computed value is less than the critical value? 4. What does it mean if you reject the null hypothesis? 5. What do you mean if you fail to reject the null hypothesis?
