This activity will help you consider how transforming data affects the mean, standard deviation, and shape of a distribution. 1. a. Use StatCrunch to generate 4O exam scores from a normal distribution with a mean of 7S and a standard deviation of 10. Name the column \"Exam Scores." b. Calculate the mean and standard deviation for your exam scores Mean = Stande deviation = c. Choose one of the exam scores and calculate its z-score. d. Create a histogram for the exam scores and sketch it here. 2. Suppose the teacher plans to adjust the scores by adding ten points to each student's score. a. Transform the exam score data by adding ten points to each score. Create a new column and name it \"Exam Scores + 10." b. Calculate the mean and standard deviation for the adjusted exam scores. Mean = Stande deviation = c. Calculate the z-score for the same student whose score you used in question 1. d. Create a histogram for the exam scores and sketch it here
