Check the model The mean of the 100 car speeds in Exercise 20 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.

Lecture 5: Probability 7.1 Random Circumstance and Interpretations of Probability -­ A few ways to think about PROBABILITY: (1) Personal or Subjective Probability -­ P(A) = the degree to which a given individual believes that the event A will happen. (2) Long term relative frequency P(A) = proportion of times ‘A’ occurs if the random experiment (circumstance) is repeated many, many times. (3) Basket Model P(A) = proportion of balls in the basket that have an ‘A’ on them. -­ Note: each time I do the experiment, the selected ball is either white or blue;; once I look, there is no more ‘probability’) -­ Note: A probability
