Points 0 3 of 1 K To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B The mean braking distance for Make A is 45 feet Assume the population standard deviation is 4 5 feet The mean braking distance for Make B is 47 feet Assume the population standard deviation is 4 3 feet At a 010 can the engineer support the claim that the mean braking distances are different for the two makes of automobiles Assume the samples are random and independent and the populations are normally distributed Complete parts a through e Click here to view page 1 of the standard normal distribution table Click here to view page 2 of the standard normal distribution table A Ho H H Ha H1 H OD Ho H1 H Ha H1 H2 OA z 2 81 OC z 1 64 E z 1 64 z 1 64 OG z 2 81 z 2 81 Part 5 of 7 b Find the critical value s and identify the rejection region s The critical value s is are 1 64 1 64 Round to two decimal places as needed Use a comma to separate answers as needed What is are the rejection region s c Find the standardized test statistic z for 2 z Round to two decimal places as needed OB Ho H H Ha H1 H2 OE Ho H H Ha 11 12 ACCESS B z 2 58 z 2 58 D z 258 OF Z 2 58 OH z 1 96 z 1 96 Ho kg 12 H 14 52 OF Ho H H H H 2 Save
