![Working with the Concepts
21. Is the lottery fair? Mega Millions is a multistate lottery in
which players try to guess the numbers that will turn up in a
drawing of numbered balls. One of the balls drawn is the Mega
Ball. Matching the number drawn on the Mega Ball increases
ones winnings. During a recent three-year period, the Mega Ball
was drawn from a collection of 15 balls numbered 1 through 15,
and a total of 344 drawings were made. For the purposes of this
exercise, we grouped the numbers into five categories: 1-3, 4-6,
and so on. If the lottery is fair, then the winning number is
equally likely to occur in any category. Following are the
observed frequencies.

a. Compute the expected frequencies.
b. Compute the value of x2
c. How many degrees of freedom are there?
d. Test the hypothesis that each of the categories is
equally likely. Use the a = 0.05 level of
significance.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcac045d5-ddb8-4d85-bea4-ee23a1a02d35%2F752c72d3-21d4-4276-81c6-7cdf42b9b1bd%2Fqijdj9k_processed.jpeg&w=3840&q=75)
