In a survey, 800 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 40 8 and upper bound 42.7. Which of the following represents a reasonable interpretation of the result? For those that are
not reasonable, explain the flaw. Complete parts (a) through (d) below.
(a) There is a 95% chance the mean number of hours worked by adults in this country in the previous week was between 40.8 hours and 42.7 hours.
O A. Flawed. This interpretation makes an implication about individuals rather than the mean.
B. Correct. This interpretation is reasonable.
BC. Flawed. This interpretation implies that the population mean varies rather than the interval
OD. Flawed. This interpretation implies that the mean is only for last week
