Significance level for the t-test: f. Decision rule: If the significance level of the obtained t statistic is greater than ____ (alpha level), we fail to reject the null hypothesis. If the significance level of the obtained t statistic is equal to or less than ____ (alpha level), we reject the null hypothesis. g. Decision: Since the significance level of the obtained t statistic is _____ and it is __________(greater or less) than ____ (alpha level), we ________(reject or fail to reject) the null hypothesis. h. Interpretation/conclusion:A hypothesis test is performed on Ho: Pa = 7 H₁: a <7 where the alternative hypothesis is the claim.
