An insurаnce cоmpаny undertаkes a study оf distracted driving. In a randоm sampling of 390 drivers, 190 admit to being regularly distracted while driving (e.g., texting, changing music, eating/drinking, etc.). Use an alpha=0.05 to test the claim that half (50%) or more of all drivers are regularly distracted while driving. Answer the following questions:H0: p [c1] 50% (enter correct sign(s))H1: p [c2] 50% (enter correct sign(s))The claim is [m1] (enter H1 or H0)The critical value on the left, if there is one = [cv1] (round to 3 decimals-if none, enter "na")The critical value on the right, if there is one = [cv2] (round to 3 decimals-if none, enter "na")The test statistic = [ts] (round to 3 decimals)The result of the hypothesis test of H0 is [result] (enter "reject H0" or "fail to reject H0")Is the claim supported? [support] (enter yes or no)
