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 50 psi. Suppose the two-tailed p-value for the test
described above (obtained from a computer printout) is p = .07. Give the proper conclusion for
the test. Use a = .05.
A) Reject H0 and conclude that , the true mean tension of the rackets, equals 50 psi.
B) There is insufficient evidence to conclude that , the true mean tension of the rackets, is
less than 50 psi.
C) There is sufficient evidence to conclude that , the true mean tension of the rackets, is less
than 50 psi.
D) Accept H0 and conclude that , the true mean tension of the rackets, equals 50 psi.
