(1 point) 50 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 50 values have a mean of 98 sec and a standard deviation of 248 sec. Use a 0.01 significance level to test the claim that the population of all watches has a mean of Osec.

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 115sec and a population standard deviation of 199sec. Use a 0.02
significance level to test the claim that the population of all
watches has a mean of 0sec (use a two-sided alternative).
