he mean systolic blood pressure of all healthy aduits is less than than 124 mm Hg. Sample data: For 273 healthy aduits, the mean systolic blood pressure level is he standard deviation is 15.96 mm Hg . The null and alemative hypotheses are \( \mathrm{H}_{6}: \mu=124 \) and \( \mathrm{H}_{1}: \mu<124 \). Find the value of the test statistic. e of the test statistic is \( \square \) o two decimal places as needed.)

Step 1

- Sample size (\( n \)) = 273 - Sample mean (\( \bar{x} \)) = (not provided in the image) - Population mean under null hypothesis (\( \mu_0 \)) = 124 mm Hg - Standard deviation (\( \sigma \)) = 15.96 mm Hg Show more…
