A- For a population with μ = 150, a raw score of X = 125 corresponds to z = -2.00. What is the standard deviation? B- For a population with σ = 15, a raw score of X = 82 corresponds to z = -0.60. What is the mean for this distribution? C- A list of exam scores shows that the raw score of X = 77 corresponds to z = -1.50 and a raw score of X = 91 corresponds to z = +2.00. Find the mean and standard deviation for the distribution of raw scores.
