Question: painiple standard deviation for these 150 infants. (c) Without computing the interval, would you expect a 97% confidence interval for the mean to be larger,

painiple standard deviation for these 150 infants. (c) Without computing the interval, would you expect a 97% confidence interval for the mean to be larger, smaller or of the same length compared to the above 95% confidence interval. (Why?) (d) Give a 97% confidence interval for the mean serum bilirubin level of 4-day old infants. Problem 8.16 Using a sample of 75 subjects, we found that the diameter of a coronary vessel has a mean of T = 2.75 mm and a standard deviation s = 0.45 mm. Assume that the diameter of this coronary vessel is normally distributed. (a) Give a 95% confidence interval for the average diameter of this coronary vessel. (b) Give the estimated standard error of the mean. (c) Using the sample mean as the population mean and the sample standard deviation as the population standard deviation, compute the probability that the diameter of a coronary vessel is less than 2 mm. 99+ home end F3 DII prt sc F12 F4 F5 F6 F7 F8 F9 F10 F11
