35 people are randomly selected and the accuracy of their wristwatches is checked, with positive errors representing watches that are ahead of the correct time, and negative errors representing watches that are behind the correct time. The 35 values have a mean of 106 sec, and a standard deviation of 238 sec. Use a 0.05 significance level to test the claim that the population of all watches has a mean of O sec. A. Define the null and the alternate hypotheses. B. Determine the test statistic. C. Determine the P-value.
