In a survey, 1100 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: 36 hours and upper bound: 48 hours. Which of the following represents a reasonable interpretation of the result? For those that are not reasonable, explain the flaw. Interpretation #1: We are 95% condent that the mean number of hours worked by adults in this country in the previous week was between 36 hours and 48 hours. C] Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. C] Flawed. This interpretation implies that the population mean varies rather than the interval. C] Flawed. This interpretation makes an implication about individuals rather than the mean. OThis is a reasonable interpretation Interpretation #2: 95% of adults in this country worked between 36 hours and 43 hours last week. D Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. ~ C] Flawed. This interpretation makes an implication about individuals rather than the mean. 0 Flawed. This interpretation implies that the mean is only for last week. O This is a reasonable interpretation Interpretation #3: 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 36 hours and 48 hours. 0 Flawed.

O 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. OThis is a reasonable interpretation Interpretation #4: There is a 95% chance the mean number of hours worked by adults in this country in the previous week was between 36 hours and 48 hours. B Flawed. This interpretation implies that the mean is only for last week. D Flawed. This interpretation makes an implication about individuais rather than the mean. (3 Flawed. This interpretation implies that the population mean varies rather than the interval. [3 This is a reasonable interpretation r . Checkeewe
