Problem 1 Each summer, many schools using the Montessori Approach conduct what is called kindergarten roundup. Parents with children, who will be kindergartners the following school year, are asked to attend the roundup. The future students are given speech and hearing screening tests as well as academic screening tests. The academic screening tests are used to alert parents as to whether their children are ready to profit from academic experiences. The following data set contains children's screening scores (Screen), and the same children's achievement scores (Achieve) at the end of their actual kindergarten year. Use the Regression Analysis/Simple Regression procedure to determine if Screen is significantly correlated with Achieve. Screen 3 6.5 65 10 Achieve 46 52 41 SO 48 66 82 4 60 Problem 2 Use the Simple Regression procedure to determine the regression equation for the following data where First is used to predict Second. Assuming the correlation is significant, what is the predicted value for Second if the subject earned a score of 80 on First? First 72 57 50 71 75 75 52 63 77 55 40 54 93 85 76 X Second 30 73 76 18 50 53 83 82 60 34 50 81 X Problem 3 A statistics instructor wishes to study the relationship between the number of absences students take and their final course grade. Assuming the correlation is significant, what is the predicted value for Grade if the number of absences reaches 12? Number of 2 A Absences Grade 98 89 83 76 84 17 68 75 80 96
