For example, A Researcher is using the confidence Interval range values that have the true value of the population mean so the variable that would be probably more useful in this particular work in other to create an interval with 95% of 60-75-year-old patients point of estimate falls under systolic blood pressure within the mean of 134 mmHg for 10 patients. What would be the confidence calculator, margin of error, sample size, mean, standard deviation and confidence level? please show the solution.

Suppose a researcher is interested in the effectiveness of a new treatment method to decrease systolic blood pressure in patients with hypertension. Assume the researcher uses an estimated pooled standard error of 21.3 mmHG, and wants to set the desired power to 90%. If the margin of error is going to be set to 20 mmHG, how many individuals should be sampled to reach 95% confidence? A. 23 B.19.84~20 C. 23.84~24 D. 21
