Question

W. D. “Skip” Broccoli works on the production line at Magnus Industries. As his supervisor, you randomly monitor his activity throughout the 40 hour workweek. Checking at 50 randomly selected times during the week, you find that “Skip” is on break (away from his job) 11 times.
a. Using a 95% confidence level, estimate the proportion of time “Skip” was on break during the week.
b. Convert your 95% estimate of the proportion (or percentage) of time “ Skip” was on break to an equivalent estimate of the total time, out of the 40 hour week, he spent on break.
