A random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.28 hours, with a standard deviation of 2.41 hours. A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.41 hours, with a standard deviation of 1.65 hours. Construct and interpret a 90% confidence interval for the mean difference in leisure time between adults with no children and adults with children (41 - 2) Let u, represent the mean leisure hours of adults with no children under the age of 18 and u represent the mean leisure hours of adults with children under the age of 18. The 90% confidence interval for (u, -42) is the range from hours to hours. (Round to two decimal places as needed.)
