A classic rock radio station claims to play an average of 50 minutes of music every hour. However, it seems that every time you turn to this station, there is a commercial playing. To investigate their claim, you randomly select 36 different hours during the next month and record what the radio station plays in each of the 36 hours. Here are the number of minutes of music in each of these hours:
44 49 45 51 49 53 49 44 47 50 46 48
(a) Construct and interpret a 90% confidence interval for the average number of minutes of music in each hour.
(b) What can you say about the radio station's claim?
