Using the data from Exercise 57, consider the total revenue per employee. Revenue is in millions of dollars, and the count of employees is given in the data table.
(a) Why are there fewer than 428 observations available for making a histogram?
(b) Find the median, mean, and standard deviation of the revenue per employee. Be sure to include units with these.
(c) Describe the shape of the histogram. Would the Empirical Rule be useful for describing how observations cluster near the mean of this ratio?
(d) Which company has the largest revenue per employee? Is it the revenue or the number of employees that makes the ratio so large for this company?
(e) A start-up firm has 15 employees. What revenue does the company need to achieve in order to be comparable to other firms in this industry?
