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 \(95 \%\) confidence interval for mean number of hours worked was lower bound: 41.7 and upper bound: 43.6. Which of the following represents a reasonable interpretation of the result? For those that are not reasonable, explain the flaw.

(a) There is a \(95 \%\) chance the mean number of hours worked by adults in this country in the previous week was between 41.7 hours and 43.6 hours.

(b) We are \(95 \%\) confident that the mean number of hours worked by adults in this country in the previous week was between 41.7 hours and 43.6 hours.

(c) \(95 \%\) of adults in this country worked between 41.7 hours and 43.6 hours 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 41.7 hours and 43.6 hours.
