A flu shot is administered during flu season. We look at the effect of the shot on individualswho received the shot versus those who did not. In a sample of 100 patients that receivedthe flu shot, the average recovery time after being infected with the flu was 4 days with astandard deviation of 1 day. What is a 95% confidence interval for the population averagerecovery time?(3.99, 4.01)(3.80, 4.20) In a sample of 100 patients that did not receive the flu shot, the average recovery time afterbeing infected with the flu was 7 days with a standard deviation of 4 days. What is a 95%confidence interval for the population average recovery time?O (6.97, 7.03)(5.97, 8.03)O (6.21, 7.79)O (6.22, 7.78)

The mean change in muscle thickness observed after a 4-week training regimen was 4 mm, and the 95% confidence interval (CI) for mean change was (-0.5, 8.5). Which is the best scientific conclusion for the effectiveness of this regimen ?
Health insurers and the federal government are both putting pressure on hospitals to shorten the average length of stay (LOS) of their patients. The average LOS in Canada is 4.6 days. A random sample of 18 hospitals in one province had a mean LOS of 3.8 days and a standard deviation of 1.7 days. Assume that the sampled population is approximately normal. You are to construct a 95% confidence interval to see if the population mean of 4.6 days is true. Answer the followings: a. What is/are the critical value(s)? b. What is the margin of error? c. Identify the 95% confidence interval for the mean. d. Interpret the interval in terms of this application. Circle the letter of the correct answer below. A. The state can be 95% confident that its mean LOS is within this interval. B. The state can be 5% confident that its mean LOS is within this interval. C. The state can be 95% confident that its mean LOS is outside this interval. D. The state can be 95% confident that its mean LOS is 3.8 days.…
