A U.S. Navy recruiting center knows from past experience that the heights of its recruits are normally distributed with mean 68 inches. The recruiting center wants to test the claim that the average height of this year's recruits is greater than 68 inches. To do this, recruiting personnel take a random sample of 64 recruits from this year and record their heights (in inches). The data is provided in the file P10_04.xlsx.© BrainMass Inc. brainmass.com June 4, 2020, 1:17 am ad1c9bdddf
