Suppose you are representing the employees at a large corporation during contract negotiations. You have a list of the salaries of all the employees at the corporation (The salaries include the many lower level employees and the few high paid management employees) and you plan to find a measure of center (e.g. mean, median, or mode).a. Which measure or center would you use to represent the employees in an effort to support your claim that the average salary of lower level employees is much lower than the national average (for lower level employees) and thus should be increased? Mean Mode Median b. Why is this the better choice?

A local park district is planning to build a recreation center. The park district conducted a poll to find out the types of physical activities the local population would be interested in. The poll was based on telephone responses from 1013 randomly selected adults. The table shows the percentages of people who expressed interest in various activities. Is it reasonable to conclude that 62% expressed interest in either biking or aerobics? A. Yes, because the percentages can always be added in relative frequency tables. B. No, because the poll is not based on a large-enough number of individuals. C. Yes, because these categories do not overlap. D. No, because these categories overlap. E. No, because the percentages in relative frequencies tables can never be added.
