← A random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.95 hours, with a standard deviation of 2.47 hours. A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.46 hours, with a standard deviation of 1.55 hours. Construct and interpret a 95% confidence interval for the mean difference in leisure time between adults with no children and adults with children (14-12₂). Let µ, 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 (4-₂) is the range from hours to hours. (Round to two decimal places as needed.) What is the interpretation of this confidence interval? A. There is 95% confidence that the difference of the means is in the interval. Conclude that there is insufficient evidence of a significant difference in the number of leisure hours. OB. There is a 95% probability that the difference of the means is in the interval Conclude that there is a significant difference in the number of leisure hours. OC. There is 95% confidence that the difference of the means is in the interval. Conclude that there is a significant difference in the number of leisure hours. OD. There is a 95% probability that the difference of the means is in the interval. Conclude that there is insufficient. evidence of a significant difference in the number of leisure hours.

K A random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.95 hours, with a standard deviation of 2.47 hours. A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.46 hours, with a standard deviation of 1.55 hours. Construct and interpret a 95% confidence interval for the mean difference in leisure time between adults with no children and adults with children (14-12) Let µ, 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 (₁-₂) is the range from hours to hours (Round to two decimal places as needed.) What is the interpretation of this confidence interval? A. There is 95% confidence that the difference of the means is in the interval. Conclude that there is insufficient evidence of a significant difference in the number of leisure hours. OB.
