Question: A sample size of 45 is used to test Null Hypothesis (Ho):u(mean) \(\ge \) 75 vs. Alternate Hypothesis (Ha): u (mean) < 75.

Given that x Bar = 72.9 and standard deviation of mean population (o) = 4.3, answer the following questions:

(A) What is the computed value of the test statistic?

(B) What distribution does the test statistic have when the null hypothesis is true?

(C) Is the alternative hypothesis one-tailed or two-tailed?

(D) What is the p-value?
