AM -vs- PM Height: 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 30
adults, the mean difference between morning height and evening
height was 5.7 millimeters (mm) with a standard deviation of 1.5
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 average height of men in 1960 was found to be 68 inches (5
feet, 8 inches). A researcher claims that men today are taller than
they were in 1960 and would like to test this hypothesis at the
0.01 significance level. The researcher randomly selects 9797 men
and records their height to find an average of 69.702069.7020
inches with standard deviation of 2.0024 inches.
