A local tennis pro-shop strings tennis rackets at the tension (pounds per square inch) requested by the customer. Recently a customer made a claim that the pro-shop consistently strings rackets at lower tensions, on average, than requested. To support this claim, the customer asked the pro shop to string 9 new rackets at 60 psi. Suppose the two-tailed P-value
for the test described above (obtained from a computer printout) is 0.08 and the sample mean is less than 60 psi. Give the proper conclusion for the test. Use a = 0.10.
