an independent random sample is selected from an approximately normal population with an unknown standard deviation. find the p-value for the given sample size and test statistic. (assume we're considering a two sided hypothesis tests in each question. round your answers to three decimal places.)
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
