10.) For which alternative hypothesis do you reject H0if |t| ≤t (α/2,N-2)?12.) In which case would testing the null hypothesis involve a two-tailed statistical test?14. What does a p-value NOT tell you?a.) The size of the largest rejection region that would not contain the observed test statisticb.) The probability that the null hypothesis is true and you would observe a test statistic more extreme than the one observedc.) The highest value of αfor which you cannot reject the null hypothesis based on the datad.) The probability that the null hypothesis is trueAns: dLevel: ModerateSection: 3.5
