35 people are randomly selected and the accuracy of their wristwatches is checked, with positive errors representing watches that are ahead of the corect time and negative errors representing watches that are behind the correct time. The 35 values have a mean of 98sec and a standard deviation 238sec. Use a 0.01 significance level to test the claim that the population of all watches has a mean of Osec. The test statistic is The P-Value is The final conclustion is A. There is sufficient evidence to warrant rejection of the claim that the mean is equal to 0 B. There is not sufficient evidence to warrant rejection of the claim that the mean is equal to 0
