Unformatted text preview: Use zscores that are actually listed in Table A. Round your answer to three decimal places . #3) The mean of x = 11 and the standard deviation of x = 7. The variable x is linearly transformed such that x new = 6 x . What is the mean of x new ? What is the standard deviation of x new ? #4) 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? #5) The median of x = 8 and the IQR of x = 9. The variable x is linearly transformed such that x new = 5 + x . What is the median of x new ? What is the IQR of x new ? #6) The mean of x = 6 and the standard deviation of x = 2. The variable x is linearly transformed such that x new = a + bx . The mean of x new = 75 and the variance of x new = 16. Suppose b is a positive number. What does a equal? What does b equal?...
