- In terms of acting, Betty White is known for starring on 3
different long running television shows (The Mary Tyler Moore Show,
The Golden Girls and Hot In Cleveland). Those three shows averaged
23.7 shows per season. However, it seems that shows are producing
few episodes per season, and Betty decides to put that to the test.
She takes a random sample of long running television programs and
determined the number of episodes in their most recent season
below:
13, 26, 23, 18, 24, 18, 19, 13, 13, 15, 16, 21, 20, 16, 26
You may assume that the data comes from a normal
distribution.
- Construct a 95% confidence interval for the average number of
episodes per season for a television program
- Based on your answer to (a), can we say that the average number
of episodes per season is lower than the value 23.7, the average
number of episodes for the shows that Betty starred in?
Explain.
