Question:

Refer to Exercise 4.24. Using relative frequencies to estimate probabilities, find which 3 consecutive months have the lowest probability of a new birth.


Data from in Exercise 4.24

(a) Consider the simplistic model that human births are evenly distributed over the 12 calendar months. If a person is randomly selected, say, from a phone directory, what is the probability that his or her birthday would be in November or December?
(b) The monthly number of births(thousands), in the United States during a recent year, are summarized in the table below. Calculate the relative frequency of births for each month and comment on the plausibility of the uniform probability model.
