Chapter 09.01 Exercise Question 12

Statistics students were surveyed and two of the questions they were asked was what type of cellphone they use (Basic, iPhone, Smart Phone that is not an iPhone) and how much sleep they typically get on a school night in hours to see if there is an association between sleep and type of phone. For the purposes of this exercise, we will consider this sample to be representative of all students at the school. The summary statistics are shown in the following table and the data are shown in the dotplots.

Using the summary statistics given, compute the MAD statistic.Round your answer to 3 decimal places, e.g. 0.583.

MAD =__________________________________

the absolute tolerance is +/-0.003

Your answer is incorrect.Try again.

Does it appear there is an association between type of cell phone used and the amount of sleep students get?

a. Yes, the small p-value means that there is strong evidence of an association between type of cell phone used and sleep.

b. No, the small p-value means that there is no evidence of an association between type of cell phone used and sleep.

c. No, the large p-value means that there is no evidence of an association between type of cell phone used and sleep.
