After surveying students around Chaffey College about GPA's and sleep patterns, the students calculated the linear correlation coefficient to be -0.287. They had a total of eight paired values for the survey. a) Is there are a linear relationship between GPA's and sleep patterns? Why? b) Is this a strong or weak, positive or negative relationship and why?
