Given the data you created in Exercise 5.6, show that multiplying or dividing by a constant multiplies or divides the standard deviation by that constant. How does this relate to what happens to the mean under similar circumstances?
Answer to relevant QuestionsUsing what you have learned from Exercises 5.6 and 5.7, transform the following set of data to a new set with a standard deviation of 1.00. Several years ago a friend of mine in the Communication Sciences department produced a diagnostic test of language problems that is still widely used. A score on her scale is obtained simply by counting the number of ...Using the distribution in Exercise 6.1, calculate z scores for X5 2.5, 6.2, and 9. Interpret these results. A set of reading scores for fourth-grade children has a mean of 25 and a standard deviation of 5. A set of scores for ninth-grade children has a mean of 30 and a standard deviation of 10. Assume that the distributions are ...In Appendix D, what is the probability that a male will have an ADDSC score greater than 50?
