Twelve second-year medical students at a local hospital measured the systolic blood pressure of the same person, they obtained the results listed below (in mmHg). Hypertension is defined to be a blood pressure level that is too high because it is 140 mmHg or greater. Assuming that the distribution is approximately normal, use a significance level of 0.05 to test the claim that the mean blood pressure level for this patient is less than 140 mmHg. What is the test statistic for this hypothesis test? 138 132 140 148 125 130 130 144 143 141 137 150 -0.8251 0.2134 -0.4268 0.7866
