A one-sample test of H0: μ = 125 against Ha: μ > 125 is carried out based on sample data from a Normal population. The SRS of size n = 15 produced a mean 132.8 and standard deviation 12.6.

What is the value of the appropriate test statistic?

Select one:

a. z = 2.40

b. t = 2.32

c. t = 2.40

d. z = 2.32

e. t = 1.76
