Question

here are 6 celebrities with some of the highest net worths (in millions of dollars) in a recent year: oprah winfrey (3200), michael jordan (1700), paul mccartney (1200), j. k. rowling (1000), 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? the range is $2250 million. (round to the nearest integer as needed.) the variance is 764.417 million dollars squared. (round to the nearest integer as needed.) the standard deviation is $\square$ million. (round to the nearest integer as needed.)

Explanation:

Step1: Recall the formula for standard deviation

The standard deviation ($s$) is the square root of the variance ($s^2$). The formula is $s = \sqrt{s^2}$.

Step2: Substitute the variance value

We know the variance is $764.417$ million dollars squared. So we calculate the square root of $764.417$.
$\sqrt{764.417} \approx 27.65$ (but we need to round to the nearest integer)

Step3: Round to the nearest integer

$27.65$ rounded to the nearest integer is $28$.

Answer:

28
