Claim: The mean systolic blood pressure of all healthy adults is less than than 122 mm Hg. Sample data: For 261 healthy adults, the mean systolic blood pressure level is 121.96 mm Hg and the standard deviation is 16.13 mm Hg. The null and alternative hypotheses are Ho: =122 and H₁: <122. Find the value of the test statistic. The value of the test statistic is -0.44 (Round to two decimal places as needed.)
