million.

(Round to the nearest integer as needed.)

Part 4

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

A.

Because the data are from celebrities with the highest net worths, the measures of variation are typical for all celebrities.

B.

Because the statistics are calculated from the data, the measures of variation cannot tell us about other celebrities.

C.

Because the data are from celebrities with the highest net worths, the measures of variation are not at all typical for all celebrities.

D.

Because the statistics are calculated from the data, the measures of variation are typical for all celebrities.

Part 5

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

Because all of the amounts end with

50,

5,

0,

00,

it appears that they are rounded to the nearest

hundred million dollars,

hundred thousand dollars,

ten million dollars,

million dollars,

so it would make sense to round the results to the nearest

ten million dollars.

hundred thousand dollars.

hundred million dollars.

million dollars.
