You take a sample of 41 American adults and find the average amount of sleep that they get per night is 7.48 hours with a standard deviation of 1.03 hours. Compute a 97% confidence interval for the mean hours of sleep that American adults get per night. Please write your answers to at least four places. Assume that all conditions necessary for inference are satisfied. Critical value: t= Standard error: Margin of error: Confidence interval: < <.
