Recently a customer made a claim that the pro-shop consistently strings rackets at lower tensions, onaverage, than requested. To support this claim, the customer asked the pro shop to string 13 new rackets at 65psi. Suppose the two-tailed P-value for the test described above (obtained from a computer printout) is 0.09.Give the proper conclusion for the test. Use α = 0.05.

• A) There is sufficient evidence to conclude that μ, the true mean tension of the rackets, is less than 65 psi.
• B) Accept H0 and conclude that μ, the true mean tension of the rackets, equals 65 psi.
• C) There is insufficient evidence to conclude that μ, the true mean tension of the rackets, is less than 65 psi.
