More on the distribution of the t statistic. Repeat the previous exercise for the two situations where the alternative is one-sided.
Exercise
Distribution of the t statistic. Assume that you have a sample of size n = 18. Draw a picture of the distribution of the t statistic under the null hypothesis. Use Table D and your picture to illustrate the values of the test statistic that would lead to rejection of the null hypothesis at the 5% level for a two-sided alternative.
