4. (10 points) A crackpot doctor believes that the use of GPS (global positioning systems in your car) is related to the number of colds people get; specifically, she hypothesizes that more hours per week using GPS is related to more colds per year . She conducts a study where she measures GPS use in hours per week (GPS) and number of colds per year (COLDS) in a sample of 10 randomly selected patients. Note: Both variables are ratio level measurements. The columns z-GPS and z-COLDS indicate the z-scores for GPS and COLDS, respectively. Subject Number GPS Z-GPS COLDS Z-COLDS 9 0.92 -0.92 2 10 1.29 5 -0.92 3 5 -0.61 6 -0.21 4 3 -1.37 1.90 5 7 0.15 -0.92 8 0.53 5 -0.92 -1.37 1.19 0.53 -0.92 9 9 0.91 6 -0.21 10 4 -0.99 7 0.49 Using alpha .05, what do the findings indicate about the researcher's hypothesis
