Question 1

A normal distribution of BMCC MAT51 scores has a standard deviation of 1.7. Find the z-scores corresponding to each of the following values: (Round to 2 decimal places) a. A score that is 1.7 points above the mean. (Hint: "x - mean = 5" is 5 above the mean) Z b. A score that is 1.7 points below the mean. c. A score that is 1.57 points above the mean. d. A score that is same as the mean.A data set follows a normal distribution. The mean of the data set is 78 and the standard deviation of the data set is 2. Find a z-score for a data value of 83 from the set. Round your answer to two decimal places
