Previously, an organization reported that teenagers spent an average of 4.5 hours per week on the phone. The organization thinks that the current mean is higher. To test the claim, 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. Suppose that a hypothesis test is conducted to test the claim that the mean hours is more than 4.5 hours per week. What are the hypotheses for the test?

A farmer uses a lot of fertilizer to grow his crops. The farmer's manager thinks fertilizer products from distributor A contain more of the nitrogen that his plants need than distributor B's fertilizer does. He takes two independent samples of four batches of fertilizer from each distributor and measures the amount of nitrogen in each batch. Fertilizer from distributor A contained 23 pounds per batch and fertilizer from distributor B contained 18 pounds per batch. Suppose the population standard deviation for distributor A and distributor B is four pounds per batch and five pounds per batch, respectively. Assume the distribution of nitrogen in fertilizer is normally distributed. Let µ1 and µ2 represent the average amount of nitrogen per batch for fertilizer's A and B, respectively. Calculate the value of the test statistic.

Suppose a researcher is testing the hypothesis Upper H 0: pequals0.4 versus Upper H 1: pless than0.4 and she finds the P-value to be 0.33. Explain what this means. Would she reject the null hypothesis? Why? Choose the correct explanation below. A. If the P-value for a particular test statistic is 0.33, she expects results no more extreme than the test statistic in about 33 of 100 samples if the null hypothesis is true. B. If the P-value for a particular test statistic is 0.33, she expects results no more extreme than the test statistic in exactly 33 of 100 samples if the null hypothesis is true. C. If the P-value for a particular test statistic is 0.33, she expects results at least as extreme as the test statistic in about 33 of 100 samples if the null hypothesis is true. D. If the P-value for a particular test statistic is 0.33, she expects results at least as extreme as the test statistic in exactly 33 of 100 samples if the null hypothesis is true. Choose the correct conclusion below. A. Since this event is unusual, she will reject the null hypothesis. B. Since this event is not unusual, she will reject the null hypothesis. C. Since this event is unusual, she will not reject the null hypothesis. D. Since this event is not unusual, she will not reject the null hypothesis.
