STAT 245 Lecture Notes - Lecture 51: Minitab, Confidence Interval, Test Statistic
Document Summary
Falls in the confidence interval, it is possible that the two population means are the. There insufficient evidence to indicate a difference in the two population means. 10. 25 a the hypothesis to be tested is. From the minitab printout, the following information is available: x. 2 and the test statistic is t x. The rejection region is two-tailed, based on n. Table 4, the rejection region is t t . 2. 069 indicate a difference in the population means. and h0 is not rejected. It is not necessary to bound the p-value using table 4, since the exact p-value is given on the printout as p-value = . 260. c. If you check the ratio of the two variances using the rule of thumb given in this section you will find: s larger. Therefore, it is reasonable to assume that the two population variances are equal.
