From a random sample of 7 students in an introductory finance class that uses group-learning techniques, the mean examination score was found to be 76.64 and the sample standard deviation was 2.7. For an independent random sample of 8 students in another introductory finance class that does not use group-learning techniques, the sample mean and standard deviation of exam scores were 71.65 and 8.4, respectively. Estimate with 99% confidence the difference between the two population mean scores; do not assume equal population variances. A Click the icon to view the Student's t distribution table. The 99% confidence interval is from a lower limit of to an upper limit of (Round to two decimal places as needed.)
A researcher collected sample data for 19 middle-aged women. The sample had a mean serum cholesterol level (measured in milligrams per one hundred milliliters) of 192.4, with a standard deviation of 8.2. Assuming that serum cholesterol levels for middle-aged women are normally distributed, find a 90% confidence interval for the mean serum cholesterol level of all women in this age group. Give the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
