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? 42 40 39 32 21 18 16 14 13.7 12.6 the range of the sample data is $ 29.4 million. (type an integer or a decimal.) the variance of the sample data is 145.24. (round to two decimal places as needed.) the standard deviation of the sample data is $ 12.05 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 sample is random. c. yes, because the standard deviation is an unbiased estimator. d. no, because the sample is not representative of the whole populatio

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt

it should be a.

hope it

c.

step-by-step explanation:

simple you would first have to get   a negative number where as 1 to be multiplied by 24 and then you would have to multiply 6 time 4 and then repeat that process until you reach your term
