Suppose we know, based on a large sample, that therisk of hepatoma among alcoholics without cirrhosis of theliver is 24%. 2 What is the smallest number of hepatomas that wouldhave to be observed among the alcoholics with cirrhosis ofthe liver for the hepatoma experience in this group to differfrom the hepatoma experience among alcoholics withoutcirrhosis of the liver? (Hint: Use a 5% probability of gettinga result at least as extreme to denote differences betweenthe hepatoma experiences of the two groups.)

The director believes that an applicant’s undergraduate grade point average (GPA) and score on the GMAT exam are helpful in predicting which applicants will be good students. To assist in this endeavor, the director asked a committee of faculty members to classify 70 of the recent students in the MBA program into two groups: (1) good students and (2) weak students. The file MBAStudents.xlsm summarizes these ratings, along with the GPA and GMAT scores for the 70 students. What are the coordinates of the centroids for the good students and the weak students? Use XLMiner’s standard data partition command to partition the data into a training set (with 60% of the observations) and validation set (with 40% of the observations) using the default seed of 12345. Use discriminant analysis to create a classifier for this data. How accurate is this…Is the lottery fair? Power ball 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 "Powerball." Matching the number drawn on the Powerball increases one's winnings. In a 17 month period, the Power ball was drawn from a collection of 35 balls numbered 1 through 35. A total of 143 drawings were made. For the purpose of this exercise, we grouped the numbers in to five categories: 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 0.10 level of significance and the P-value method with the TI-84 Plus calculator.
