Claim: The mean systolic blood pressure of all healthy adults is less than than 119 mm Hg. Sample data: For 293 healthy adults, the mean systolic blood pressure level is 118.57 mm Hg and the standard deviation is 15.43 mm Hg. The null and alternative hypotheses are H0: μ=119 and H1: μ<119. Find the value of the test statistic.

Claim: The mean systolic blood pressure of all healthy adults is less than 125 mm Hg. Sample data: For 290 healthy adults, the mean systolic blood pressure level is 124.79 mm Hg and the standard deviation is 16.03 mm Hg. The null and alternative hypotheses are H0: mean = 125 and H1: mean < 125. Find the value of the test statistic. The value of the test statistic is __ (round to two decimal places as needed.)
