Suppose annual salaries for sales associates from a particular store have a mean of $32,500 and a standard deviation of $2,500. a. Use Chebyshev's theorem to calculate the percentage of sales associates with salaries between $27,500 and $37,500. (1 point) b. Suppose that the distribution of annual salaries for sales associates at this store is bell-shaped, Use the empirical rule to calculate the percentage of sales associates with salaries between $27,500 and $37,500. (1 point) c. Use the empirical rule to determine the percentage of sales associates with salaries less than $27,500.(1 point) C. d. Still suppose that the distribution of annual salaries for sales associates at this store is bell-shaped. A sales associate makes $42,000. Should this salary be considered an outlier? Explain.
