Question

4. 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 68 psi. Suppose the two-tailed P-value for the test described above (obtained from a computer printout) is 0.07. Find the conclusion for the test at the 5% significance level.

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 68 psi. Suppose the two-tailed P-value for the test described above (obtained from a computer printout) is 0.07. Find the
conclusion for the test at the 5% significance level.
There is sufficient evidence to conclude that u, the true mean tension of the rackets, is less than 68 psi.
O a.
There is insufficient evidence to conclude that u, the true mean tension of the rackets, is less than 68 psi.
Ob.
Accept H o and conclude that p, the true mean tension of the rackets, equals 68 psi.
C.
Reject H o and conclude that u, the true mean tension of the rackets, equals 68 psi.
