random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.72 hours, with a standard deviation of 2.39 hours. A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.22 hours, with a standard deviation of 1.92 hours. Construct and interpret a 95% confidence interval for the mean difference in leisure time between adults with no children and adults with children 12. Let 1 represent the mean leisure hours of adults with no children under the age of 18 and 2 represent the mean leisure hours of adults with children under the age of 18. The 95% confidence interval for 12 is the range from nothing hours to nothing hours. (Round to two decimal places as needed.)
