Question
A country's Energy Information Administration monitors all nuclear power plants operating in that country. The table to the right lists the number of active nuclear power plants operating
in each of a sample of 10 states.
Full data set o
Number of
State Power Plants State Power Plants
Number of
10
a. Find the range, variance, and standard deviation of this data set.
range =O
Sample variance, s = (Round to three decimal places as needed.)
Sample standard deviation, s=(Round to three decimal places as needed.)
b. Eliminate the largest value from the data set and repeat part a. What effect does dropping this measurement have on the measures of variation found in part a?
range =O
s = (Round to three decimal places as needed.)
s=U (Round to three decimal places as needed.)
What effect does dropping this measurement have on the measures of variation found in part a? Choose the correct answer below.
O A. The range decreases, but the variance and standard deviation stay the same
O B. It increases the measures of variation.
OC. It decreases the measures of variation.
OD. There is no effect on the measures of variation.
c. Eliminate the smallest and largest values from the original data set and repeat part a. What effect does dropping both of these measurements have on the measures of variation found in part a?
range =O
s*=U (Round to three decimal places as needed.)
s=U (Round to three decimal places as needed.)
What effect does dropping both of these measurements have on the measures of variation found in part a? Choose the correct answer below.
O A. The range decreases, but the variance and standard deviation stay the same
