Extracted text: Provide an appropriate response. 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 6 new rackets at 42 psi. Suppose the two-tailed P-value for the test described above (obtained from a computer printout) is 0.07. Give the proper conclusion for the test. Use a= 0.05. A) There is insufficient evidence to conclude that u, the true mean tension of the rackets, is less than 42 psi. B) There is sufficient evidence to conclude that u, the true mean tension of the rackets, is less than 42 psi. Reject Ho and conclude that µ, the true mean tension of the rackets, equals C) 42 psi. D) Accept Ho and conclude that µ, the true mean tension of the rackets, equals 42 psi.
