A random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.25. hours, with a standard deviation of 2.32 hours. A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.05 hours, with a standard deviation of 1.66 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 _____ hours to _____ hours.

(Round to two decimal places asneeded.)

What is the interpretation of this confidenceinterval?
