Unformatted text preview: ecisely, the confidence interval includes every potential value that would not have been rejected had it been the value assumed by the null hypothesis. When you do a single ­sample t ­test, the confidence interval you compute is the confidence interval for the population mean. This interval contains all values of µ0 such that the null hypothesis µ = µ0 would not be rejected based on the sample you collected, using a two ­ tailed test. To work out what the confidence interval should be, let’s think about when the null hypothesis µ = µ0 will be rejected. The t statistic for a single ­sample t ­test is t= M " µ0 SE A two ­tailed test reject...
