Question

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), paul mccartney (1200), j. k. rowling (1000), and jerry seinfeld (950). find the range, variance, and standard deviation for the sample data. what do the results tell us about the precision of the population of all celebrities? based on the nature of the amounts, what can be inferred about their precision? the range is $4550 million. (round to the nearest integer as needed.) the variance is 3,444,417 million dollars squared. (round to the nearest integer as needed.) the standard deviation is $ million. (round to the nearest integer as needed.)

Explanation:

Step1: Recall standard - deviation formula

The standard deviation $\sigma=\sqrt{\text{Variance}}$.

Step2: Substitute given variance value

Given variance $= 3444.417$. Then $\sigma=\sqrt{3444.417}$.

Step3: Calculate and round

$\sigma=\sqrt{3444.417}\approx59$ (rounded to the nearest integer).

Answer:

59
