In a test of the hypothesis H0: μ=59 versus Ha: μ>59, a sample of n=100 observations possessed mean x=58.3 and standard deviation s=4.6. Find and interpret the p-value for this test. The p-value for this test is enter your response here. (Round to three decimal places as needed.) Interpret the result. Select the correct choice below and fill in the answer box to complete your choice. (Round to three decimal places as needed.) A. The probability (assuming that Ha is true) of observing a value of the test statistic that is at most as contradictory to the null hypothesis is enter your response here. B. The probability (assuming that H0 is true) of observing a value of the test statistic that is equal to the null hypothesis is enter your response here. C. The probability (assuming that H0 is true) of observing a value of the test statistic that is at least as contradictory to the null hypothesis is enter your response here.

Claim: The mean systolic blood pressure of all healthy adults is less than than 120 mm Hg. Sample data: For 276 healthy adults, the mean systolic blood pressure level is 119.61 mm Hg and the standard deviation is 14.88 mm Hg.
