Unformatted text preview: Use a z-score that is actually listed in Table A. Round your answer to two decimal places. #4) The mean of x = 11 and the standard deviation of x = 7. The variable x is linearly transformed such that x new = 6x. What is the mean of x new ? What is the standard deviation of x new ? #5) The mean of x = 10 and the standard deviation of x = 4. The variable x is linearly transformed such that x new = a + bx. The mean of x new = 35 and standard deviation of x new = 12. Suppose b is a positive number. What does a equal? What does b equal? From book: 1.126 (page 74) Explicitly give Tonyas standardized score, rounded to four decimal places. Explicitly give Jermaines standardized score, rounded to four decimal places. 1.128 (page 74) Round Joses standardized score to four decimal places. Use that rounded number to solve for the final answer. Express your final answer to four decimal places....
