The true average diameter of ball bearings of a certain type is supposed to be 0.5 inch.

Question:

The true average diameter of ball bearings of a certain type is supposed to be 0.5 inch. What conclusion is appropriate when testing H0: µ = 0.5 versus Ha: µ = 0.5 inch each of the following situations:
a. n = 13, t = 1.6, a = .05
b. n = 13, t = - 1.6, a = .05
c. n = 25, t = - 2.6, a = .01
d. n = 25, t = - 3.6
