A normal distribution of BMCC MAT51 scores has a standard deviation of 1.5. Find the z-scores corresponding to each of the following values: (Round to 2 decimal places) a. A score that is 1.5 points above the mean. (Hint: "x - mean = 5" is 5 above the mean) z= b. A score that is 1.5 points below the mean. z= c. A score that is 1.36 points above the mean. z= d. A score that is same as the mean. z=​
