Find 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.

1. What do the results tell us about the population of all celebrities?

2. Based on the nature of the amounts, what can be inferred about their precision?

250 200 185 175 165 165 150 150 150 150

Mean = 174

Median = 165

Mode = 150

Range = 100

Mid-range = 165-150 = 15

1) only few population of the celebrities have high net-worth

2) very low precision as their is a wide range in the variation of their net worth

Step-by-step explanation:

250 200 185 175 165 165 150 150 150 150

Arranged in ascending order =

150 150 150 150 165 165 175 185 200 250

Mean = (150 + 150 + 150 + 150 + 165 + 165 + 175 + 185 + 200 + 250) / 10

Mean = 1740/10

Mean = 174

Median = (165+165) / 2

Median = 165

Mode = 150

Range = 250-150

Range = 100

Mid-range = 165-150 = 15

1) only few population of the celebrities have high net-worth

2) very low precision as their is a wide range in the variation of their net worth
