In a survey, 1400 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 number of hours worked was lower bound: 41.8 and upper bound: 45.8. Which of the following represents a reasonable interpretation of the result? For those tha not reasonable, explain the flaw. Complete parts (a) through (d) below. O A. Flawed. This interpretation implies that the mean is only for last week. O B. Flawed. This interpretation makes an implication about individuals rather than the mean. O C. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. O D. Correct. This interpretation is reasonable. (d) We are 95% confident that the mean number of hours worked by adults in a particular area of this country in the previous week was between 41.8 hours and 45.8 hours. O A. Flawed. This interpretation implies that the population mean varies rather than the interval. O B. Flawed. The interpretation should be about the mean number of hours worked by adults in the whole country, not about adults in the particular area. OC. Correct. This interpretation is reasonable. O D. Flawed. This interpretation makes an implication about individuals rather than the mean.
