The null distribution for test statistic x is N(4;82). The rejection region is fx 20g. What is the signi cance level and power of this test? answer: 20 is two standard deviations above the mean of 4. Thus, signi cance = P(x 20jH 0) ˇ0:025 The question about power was a trick: we can’t compute the power without an alternative distribution.

Because our significance level is 5% and .4% < 5%, we reject the null hypothesis and conclude that Newcomb’s measurements were not consistent with the currently accepted figure. We did not have to use the sample average as our test statistic. We could have used a t-statistic…
