In a study comparing the systolic blood pressure of individuals sitting and standing, 9 subjects had their blood pressure measured standing, while 10 individuals has their blood pressure measured sitting. The investigator swims 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 3% level of signicance, assuming equal variances, the rejection region would be: Question 7 t > 2.368 t 2.368 |Z| > 2.17 ~ |t| > 2.17
