In a survey, 13001300 adults in a certain country were asked how many hours they worked in the previous week. Based on the results, a 95% confidence interval for mean number of hours worked was lower bound: 39.639.6 and upper bound: 43.943.9. Which of the following represents a reasonable interpretation of the result? For those that are not reasonable, explain the flaw. (a) There is a 95% chance the mean number of hours worked by adults in this country in the previous week was between 39.639.6 hours and 43.943.9 hours. A. Flawed.
