Listed below are the top 10 annual salaries (in millions of dollars) of TV personalities. Find the range, variance, and standard deviation for the sample data. Given that these are the top 10 salaries, do we know anything about the variation of salaries of TV personalities in general?
39 38 37 30 21 18 17 15 14.6 13.2
The range of the sample data is $___ million. (Type an integer or a decimal.)
The variance of the sample data is
nothing. (Round to two decimal places as needed.)
The standard deviation of the sample data is $
nothing million.
(Round to two decimal places as needed.)
Is the standard deviation of the sample a good estimate of the variation of salaries of TV personalities in general?
A. No, because there is an outlier in the sample data.
B. Yes, because the standard deviation is an unbiased estimator.
C. Yes, because the sample is random.
D. No, because the sample is not representative of the whole population.

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
