In a study comparing the systolic blood pressure of individuals sitting and standing, 14 subjects had their blood pressure measured standing, while 8 individuals has their blood pressure measured sitting. The investigator planned to test the hypothesis that the mean blood pressure readings are the same sitting and standing (the subjects remained in each position for 5 minutes). If the investigator tests at the 7% level of significance, assuming equal variances, the rejection region would be:

The investigator planned to test the hypothesis that the mean blood pressure readings are the same sitting and standing (the subjects remained in each position for 5 minutes). If the investigator tests at the 7% level of significance, assuming equal variances, the rejection region would be: O |Z| > 1.812 o t< -1.914 or t > 1.914 O t> 1.914 o t| > 1.812
