Check the model The mean of the 100 car speeds in Exercise 26 was 23.84 mph, with a standard deviation of 3.56 mph. a) Using a Normal model, what values should border the middle 95% of all car speeds?...

Check the model The mean of the 100 car speeds in Exercise 26 was 23.84 mph, with a standard deviation of 3.56 mph.

a) Using a Normal model, what values should border the middle 95% of all car speeds?

 b) Here are some summary statistics

From your answer in part a, how well does the model do in predicting those percentiles? Are you surprised? Explain.
