It is widely accepted that people are a little taller in the morning than at night. Here we perform a test on how big the difference is. In a sample of 35 adults, the mean difference between morning height and evening height was 5.5 millimeters (mm) with a standard deviation of 1.26955 mm. Test the claim that, on average, people are more than 5 mm taller in the morning than at night. Test this claim at the 0.05 significance level. (a) Find the test statistic. (b) Find the critical value. (c) Is there sufficient data to support the claim? Yes No
