The Nielsen Company is a global information and media company and one of the leading suppliers of media information. The company is planning a pilot study of the amount of time that college students spend watching videos on their phones. 

The data below are the number of hours per month spent watching videos by a random sample of eight college students. 7 9 1 6 13 10 3 5 

Use these data to compute the mean and the standard deviation of these values and then obtain a 90% confidence interval for the average time watching videos by college students. Give the “correct” interpretation of your interval.
