Refer to the results of #1 as needed. A) Determine the monthly milk production values that correspond to z = -3, -2, -1, 0, 1, 2, and 3. Copy and paste this table into the answer field and then enter your responses. Monthly Milk Production Z-score -3 -2 -1 0 1 2 3 B) Copy and paste the chart provided below into the answer field below. Refer to the your results in part A) to complete the chart. Insert the milk production values that are boundaries for the indicated classes based on the z-scores. Complete the frequency column by referring to the milk production values given at the start of the Case Study. Class Boundaries Class Z-scores Frequency – to -3 -3 to -2 -2 to -1 -1 to 0 0 to 1 1 to 2 2 to 3 3 to C) Copy and paste the provided chart into the answer field below. Use the results of part B) to determine the percentage of values within 1, 2, and 3 standard deviations of the mean. Interval of Milk Production Interval of z scores Percentage within 1 standard deviation of the mean – 1 to 1 within 2 standard deviations of the mean -2 to 2 within 3 standard deviation of the mean -3 to 3 D) Based on the results of part C) and the Empirical Rule, do you think the data is approximately normally distributed? Explain your answer.
