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 14 new rackets at 65 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 65 psi. Give the proper
conclusion for the test. Use a = 0.10.
A. Accept H, and conclude that, the true mean tension of the rackets, equals 65 psi.
B. Reject H, and conclude that u, the true mean tension of the rackets, equals 65 psi.
C. There is sufficient evidence to conclude that, the true mean tension of the rackets, is less than 65 psi.
D. There is insufficient evidence to conclude that the true mean tension of the rackets, is less than 65 psi.
