Question

Watch Corporation of Switzerland claims that its watches on average will neither gain nor lose time during a week. A sample of 18 watches provided the following gains (+) or losses (−) in seconds per week.


−0.44	−0.24	−0.32	−0.30	+0.41	−0.28	+0.48	+0.24	−0.13
−0.28	−0.62	−0.45	−0.49	−0.57	−0.07	−0.20	−0.53	+0.06

State the null hypothesis and the alternate hypothesis.
State the decision rule for 0.01 significance level. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)
Is it reasonable to conclude that the mean gain or loss in time for the watches is 0? Use the 0.01 significance level.
Estimate the p-value.
