Use the following to answer the questions below:

Many major television networks air coverage of the incoming election results during primetime hours. The provided boxplot displays the amount of time (in minutes) spent watching election coverage for a random sample of 25 U.S. adults. In this sample, the average time spent watching election coverage was 80.44 minutes with standard deviation of 43.99 minutes.

A horizontal boxplot depicts the results of the time spent watching election coverage for 25 U.S. adults. The horizontal axis is labeled, Hours spent watching election coverage and ranges from 0 to 180 in increments of 20. The whiskers of the box plot range from 2 to 168 and the box ranges from 50 to 115 with a median at 70. All values are approximate.


Construct a 90% confidence interval for the average amount of time U.S. adults spent watching election coverage. Use two decimal places in your margin of error.

▸ 71.33 to 89.55 hours

▸ 66.24 to 94.64 hours

▸ 68.14 to 92.74 hours

▸ 65.39 to 95.49 hours
