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 ($s^2$). So, if the variance is $764.417$ million dollars squared, we need to take the square root of $764.417$.

Step2: Calculate the square root

We calculate $\sqrt{764.417}$. Using a calculator, $\sqrt{764.417} \approx 27.65$. Rounding to the nearest integer, we get $28$.

Answer:

28
