4.4 Find the p-value. An independent random sample is selected from an approximately normal

population with an unknown standard deviation. Find the p-value for the given set of hypotheses

and T test statistic. Also determine if the null hypothesis would be rejected at α = 0.05.

(a) HA : μ > μ0, n = 11, T = 1.91

(b) HA : μ < μ0, n = 17, T = −3.45

(c) HA : μ 6= μ0, n = 7, T = 0.83

(d) HA : μ > μ0, n = 28, T = 2.13
