Question 4 0.5 pts A data set has a mean of 44. In this data set, a raw score X-40 corresponds to the standardized score z-1. What is the standard deviation for this data set? Hint:take advantage of the formula for Z-score Question 5 0.5 pts A data set has a standard deviation of 2.5. In this data set, a raw score X-30 corresponds to the standardized score z = 1.30. What is the mean of this data set? Hint:take advantage of the formula for Z-score Question 6 0.5 pts A data set has a standard deviation of 5. In this data set, a raw score of X-10 corresponds to the standardized score z--2.40 (note negative value). What is the mean of this data set? Question 7 0.5 pts A very large class just had a math exam, and the scores have a mean of 75 and a standard deviation of 8. My math score is 1.6 standard deviations below the mean. What is my score on this math exam?
