When you have your blood pressure taken, the larger number is the systolic blood pressure. Researchers looked at whether men and women have different systolic blood pressure levels. Use the accompanying technology output to report and interpret the 95% confidence interval for the difference in mean systolic blood pressure for men and women. Does this support the hypothesis that men and women differ in mean systolic blood pressure? Explain Click the icon to view the technology output. Report and interpret the 95% confidence interval Select the correct choice below and fill in any answer boxes to complete your choice. (Typo integers or decimals. Do not round. Use ascending order.) O A. There is a 95% chance that the difference in mean systolic blood pressure between women and men is between and O B. The difference in mean systolic blood pressure between women and men is definitely between and OC. It can be stated with 95% confidence that the difference in mean systolic blood pressure between women and men is between and

To construct a confidence interval for the difference between two population means , -H3, use the formula shown below when both population standard deviations are known, and either both populations are normally distributed or both n, a 30 and n, 2 30. Also, the samples must be randomly selected and independent. o 03 - 03 2 П The descriptive statistics for the annual salaries from a random sample of microbiologists from two regions are shown below. Construct a 95% confidence interval for the difference between the mean annual salaries. * = $102.290, n. = 40, and on = $8935; X2 = $85,390, n2 = 37, and a =58945 + ng Complete the 95% confidence interval for 1-12 below. $<-<$ (Round to the nearest dollar as needed.)
