In a survey. 700 adults in a certain country were asked how many hours they worked in the previous week. Based on the results, a 95% condence interval for mean number of hours worked was lower bound: 41.9 and upper bound: 43.8. Which of the following represents a reasonable interpretation of the result? For those that are not reasonable, explain the aw. 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 41.9 hours and 43.8 hours. 0 A. Flawed. This interpretation implies that the mean is only for last week. 0 B. Correct. This interpretation is reasonable. 0 c. Flawed. This interpretation implies that the population mean varies rather than the interval. 0 D. Flawed. This interpretation makes an implication about individuals rather than the mean. (b) We are 95% condent that the mean number of hours worked by adults in this country in the previous week was between 41.9 hours and 43.8 hours. 0 A. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. 0 B. Correct. This interpretation is reasonable. 0 C. Flawed. This interpretation makes an implication about individuals rather than the mean. 0 D. Flawed. This interpretation implies that the population mean varies rather than the interval. (c) 95% of adults in this country worked between 41.9 hours and 43.8 hours last week. 0 A. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. 0 B. Correct. This interpretation is reasonable. 0 C. Flawed. This interpretation makes an implication about individuals rather than the mean. 0 D. Flawed. This interpretation implies that the mean is only for last week. (d) We are 95% condent that the mean number of hours worked by adults in a particular area of this country in the previous week was between 41.9 hours and 43.8 hours. 0 A. Correct. This interpretation is reasonable. 0 B. Flawed. This interpretation implies that the population mean varies rather than the interval. 0 C. Flawed. This interpretation makes an implication about individuals rather than the mean. 0 D. 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
