Question
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 10 new rackets at 41 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= 0.10.
CA Accept Ho and conclude that u, the true mean tension of the rackets, equals
41 psi.
B)
There is insufficient evidence to conclude that u, the true mean tension of
the rackets, is less than 41 psi.
There is sufficient evidence to conclude that u, the true mean tension of the
C)
rackets, is less than 41 psi.
Reject Ho and conclude that u, the true mean tension of the rackets, equals
D)
41 psi.
