Based on a random sample of 1140 adults, the mean amount of sleep per night is 8.56 hours. Assuming the population standard deviation for amount of sleep per night is 1.3 hours, construct and interpret a 90% confidence interval for the mean amount of sleep per night. A 9090% confidence interval is (nothing,nothing). (Round to two decimal places as needed.) Interpret the confidence interval.
