Question
(c) Suppose the score of 59.5 in the traditional course was incorrectly recorded as 595. How does this affect the range?
The range is now
(Type an integer or a decimal. Do not round.)
How does this affect the standard deviation?
The standard deviation is now
(Round to three decimal places as needed.)
What property does this illustrate?
O A. The standard deviation is resistant, but the range is not resistant.
B. Neither the range nor the standard deviation is resistant.
C. Both the range and the standard deviation are resistant.
D. The range is resistant, but the standard deviation is not resistant.
