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 43 feet At a 0 10 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 untury uit cian and state to an a What is the claim A The mean braking distance is different for the two makes of automobiles OB The mean braking distance is the same for the two makes of automobiles OC The mean braking distance is less for Make A automobiles than Make B automobiles OD The mean braking distance is greater for Make A automobiles than Make B automobiles What are Ho and Ha A Ho H H2 Ha H1 H2 OD Ho ky2M2 Ha H1 H2 b Find the critical value s and identify the rejection region s The critical value s is are OB Ho H1 H Ha H1 H2 OE Ho H H2 Ha H1 H2 dad Uco a comma to separate answers as needed C Ho Hy H2 Ha 12 OF Ho H H Ha H1 H
