45 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 45 values have a mean of 104sec and a population standard deviation of 215sec. Use a 0.02 significance level to test the claim that the population of all watches has a mean of (sec (use a two-sided alternative). The test statistic is The P-Value is The final conclustion is A. There is not sufficient evidence to warrant rejection of the claim that the mean is equal to 0 B. There is sufficient evidence to warrant rejection of the claim that the mean is equal to 0
