In a survey, 600 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: 41.5 and upper bound: 45.6. 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 41.5 hours and 45.6 hours.

a. flawed. this interpretation makes an implication about individuals rather than the mean.

b. flawed. this interpretation implies that the mean is only for last week.

c. correct

d. flawed. this interpretation implies that the population mean varies rather than the interval
