the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given questions. Listed below are the highest amounts of net worth (in millions of dollars) of all celebrities. What do the results tell us about the population of all celebrities? Based on the nature of the amounts, what can be inferred abou their precision? 275 200 185 165 160 160 145 145 145 145 (lype an integer or a decimal rounded to one decimal place as needed.) e. What do the results tell us about the population of all celebrities? OA. The results tell us that the most common celebrity net worth is the mode, but all other celebrities are expected to have net worths approximately equal to the mean, median, or midrange. OB. The results tell us that all celebrities are expected to have amounts of net worth approximately equal to one of the measures of center found in parts (a) through (d). OC. Apart from the fact that all other celebrities have amounts of net worth lower than those given, the results in parts (a), (b), and (d) do not given meaningful results. However, the result from part (c) shows that the most common celebrity net worth is equal to the mode. O D. Apart from the fact that all other celebrities have amounts of net worth lower than those given, nothing meaningful can be known about the population. Based on the nature of the amounts, what can be inferred about their precision? OA. The values all end in 0 or 5, so they appear to be rounded estimates. OB. The values are all whole numbers, so they appear to be accurate to the nearest whole number. OC. Since celebrity information is public, these values can be assumed to be unrounded. OD. Since no information is given, nothing can be said about the precision of the given values.

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
