Find the p-value, Part I. 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?μ0,n=7,T =0.83 (d) HA :μ>μ0,n=28,T =2.13
