Here are 6 celebrities with some of the highest net worths (in millions of dollars) in a recent year: George Lucas (5500), Steven Spielberg (3700), Oprah Winfrey (3200), Michael Jordan (1700), David Copperfield (1000), and Jerry Seinfeld (950) . Find the range, variance, and standard deviation for the sample data. What do the results tell us about the population of all celebrities? Based on the nature of the amounts what can be inferred about their precision? Names Net Worth (in The range is $ million. George Lucas 5500 (Round to the nearest integer as needed.) Steven Spielberg 3700 Oprah Winfrey 3200 The variance is million dollars squared. Michael Jordan 1700 (Round to the nearest integer as needed.) David Copperfield 1000 The standard deviation is $ | million. Jerry Seinfeld 950 (Round to the nearest integer as needed.) What do the results tell us about the population of all celebrities? O A. Because the statistics are calculated from the data, the measures of variation cannot tell us about other celebrities. O B. Because the statistics are calculated from the data, the measures of variation are typical for all celebrities. O C. Because the data are from celebrities with the highest net worths, the measures of variation are typical for all celebrities. O D. Because the data are from celebrities with the highest net worths, the measures of variation are not at all typical for all celebrities. Based on the nature of the amounts, what can be inferred about their precision? Because all of the amounts end with | it appears that they are rounded to the nearest so it would make sense to round the results to the nearest hundred million dollars, 5 hundred million dollars. ten million dollars, 0. ten million dollars. e hundred thousand dollars, 50, million doll 00. million dollars, hundred thousand dollars. ah it appears so it would : nearest
