State the null and alternate hypotheses escIs the lottery fair? Powerball 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 ballsdrawn is the "Powerball." Matching the number drawn on the Powerball increases one's winnings. In a 17 month period, the Powerball was drawn from acollection of 35 balls numbered 1 through 35. A total of 147 drawings were made. For the purpose of this exercise, we grouped the numbers in to fivecategories: 1-7, 8-14, 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.Test the hypothesis that each of the categories is equally likely. Use the 0.05 level of significance and the critical value method with the table.Category 1-7 8-14 15-21 22-28 29-35Observed 33 22 3531 26Send data to ExcelPart 1 of 7Compute the expected frequencies.Category1-7 8-14 15-21 22-28 29-35Expected frequency 29.4 29.4 29.4 29.4 29.4Part 2 of 7Compute the value of 2.
