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
Give the proper conclusion for the test. Use
◦ There is insufficient evidence to conclude that μ, the true mean tension of the rackets, is less than 42 psi.
◦ Accept H
0 and conclude that μ, the true mean tension of the rackets, equals 42 psi.
◦ Reject H
0 and conclude that μ, the true mean tension of the rackets, equals 42 psi.
◦ There is sufficient evidence to conclude that μ, the true mean tension of the rackets, is less than 42 psi.
