WebDo you just want to do a hypothesis test for the sample mean 6.07 against the null of mean 4? Then qnorm(0.05, 4, 3, FALSE) will give you the 95% rejection region (one-sided hypothesis), and (6.07 - 4) / (3/sqrt(10)) will give you the test statistic. – WebStep 2: Check conditions. We want to use these n=5 n = 5 differences to construct a confidence interval for the mean difference. Since we don't know the population standard deviation of the differences, we'll have to use the sample standard deviation in its place.
