In a survey, 1500 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: 39.5 and upper bound: 44.6. 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 39.5 hours and 44.6 hours. O A. Flawed. This interpretation implies that the mean is only for last week B. Flawed. This interpretation implies that the population mean varies rather than the interval O C. Correct. This interpretation is reasonable O D. Flawed. This interpretation makes an implication about individuals rather than the mean, (b) We are 95% confident that the mean number of hours worked by adults in this country in the previous week was between 39.5 hours and 44.6 hours. O A. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval, O B. Flawed. This interpretation implies that the population mean varies rather than the interval. O C. Correct. This interpretation is reasonable. O D. Flawed. This interpretation makes an implication about individuals rather than the mean, (c) 95% of adults in this country worked between 39.5 hours and 44.6 hours last week O A. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. O B. Correct. This interpretation is reasonable. C. Flawed. This interpretation makes an implication about individuals rather than the mean O D. Flawed. This interpretation implies that the mean is only for last week (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 39.5 hours and 44.6 hours A. Flawed, This interpretation makes an implication about individuals rather than the mean 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 O C. Flawed. This interpretation implies that the population mean varies rather than the interval O D. Correct. This interpretation is reasonable
