part d) What? is/are the rejection? region(s)?

part e) Find the standardized test statistic z for ?1??2. (Round to two decimal places as needed) part f) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below.

part g) Interpret the decision in the context of the original claim below

At the ___?% significance? level, there _______ sufficient evidence to __________the claim that the mean braking distance for Make A automobiles is _______________ the one for Make B automobiles.

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 MakeAis 43 feet. Assume the population standard deviation is 4.? feet. The mean braking distanoe for Make B is 45 feet. Assume the population standard deviation is 4.4 feet. At ct = 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 'I of the standard normal distribution table. Click here to View page 2 of the standard normal distribution table. (a) Identify the claim and state H0 and H3. What is the claim? 0 A. The mean braking distance is different for the two makes of automobiles. O B. The mean braking distance is greater for Make A automobiles than Make B automobiles. O C. The mean braking distance is less for MakeA automobiles than Make B automobiles. O D. The mean braking distance is the same for the two makes of automobiles
