7. A sociologist wanted to estimate the difference in the amount of daily leisure time (in hours) of adults who do not have children under the age of 18 years and adults who have children under the age of 18 years. A random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.62 hours, with a standard deviation of 2.43 hours. A random sample of 40 adults with children under the age of 18 years results in a mean daily leisure time of 4.10 hours, with a standard deviation of 1.82 hours. Construct a 95% confidence interval for the mean difference in leisure time between adults with no children and adults with children.

Do you think Benjamin Strong would have agreed with the
words below spoken by Franklin Roosevelt in 1933?
“The world will not long be lulled by the specious
fallacy of achieving a temporary and probably artificial stability
in foreign exchange on the part of a few large countries ... The
sound internal economic situation of a nation is a greater factor
in its well-being than the price of its currency.”
