Consider the following competing hypotheses and sample data.

H0: m ≤ 150

HA: m > 150

n = 30 T - = 200 T+ = 265

a. Assuming that the sampling distribution of T is normally distributed, determine the value of the test statistic.

b. Calculate the p-value.

c. At the 5% significance level, what is the conclusion? Explain.
