A clinic measured the systolic blood pressure for a random sample of 10 patients. The resulting 95% confidence interval for the mean systolic blood pressure of all the patients at this clinic was (111.3, 129.5). What was the margin of error for this confidence interval? 9.1 18.2 120.4 240.8

Find the 99% confidence interval (CI) and margin of error (ME) for systolic blood pressures for women aged 18-24 when: n=92, x̄=114.9, σ=13.2. Interpret your results.
Adi S.
Of 127 patients selected at random from a clinic, 34 were found to have high blood pressure. Construct a 95% confidence interval for the true proportion of all patients at this clinic that have high blood pressure. Round your answer to 3 decimal places. Lower Limit = Upper Limit = Show the confidence interval calculated
