the head of public safety notices that the average driving speed in a parking structure averages 2.55 mph with a standard deviation of 0.5 mph. after a school speed limit sign of 5 mph is placed at an intersection, the first 30 cars travel past at an average speed of 2.76 mph. a. using the five steps of hypothesis testing, was the group of 30 cars' mph different from the driving speed of cars in general in this parking lot? (use the .05 significance level.) be sure to sketch the distributions involved. be sure to fully state the five steps and show all calculations/work. b. additionally, explain the logic of what you did to a person who understands hypothesis testing for studies in which the sample consists of a single individual but is unfamiliar with hypothesis testing involving a sample of more than one individual. (be sure your explanation includes a discussion of the distribution of means--what it is, what it is made of, the concept of how it is created, how it's characteristics are created, its role in the overall hypothesis testing process.)
