a) What is the estimated standard error for the half?

b) Construct a 99% confidence interval for the population mean from which the 10 individuals can be considered to make up a random sample

    A resting systolic blood pressure (BP) of 120 mm Hg is stated to be the population mean for women. This was based on research conducted by several researchers on women from the healthy general public. Consider 20 first-year resident female doctors drawn at random. The resting systolic BP measured using an electronic sphygmomanometer are listed below. Is the sample significantly different from the population? State the null and alternative hypotheses Set the criteria for a decision: two-tailed test with a...
