An organization uses an employee performance evaluation system that assigns each worker a score between 0 and 200. Over the years it turned out that the rankings of 1,000 employees were normally distributed with an average of 100 and standard deviation (SD) of 15. A. Consider the central part of the distribution. 62% of employees have earned the scores between (fill in the blanks)__ and which is considered a range for normal (or average) employee performance. (Make sure to provide rankings, NOT the z scores). L - B. What percentage of employees earned rankings between 75 and 118? (Show you work: draw picture, highlight or circle your answer. Do not round your answer for this part.) C. The scores below 70 are considered "performance deficient." Considering that the current workforce of the company is 34,019, how many such people can be found in its workforce?
