If the variance of the data \(2,4,5,6,8,17\) is 23.33 , then the variance of \(4,8,10,12,16,34\) will be
- A 93.32
- B 25.33
- C 23.33
- D 48.66
Answer & Solution
Correct Answer
(A) 93.32
Step-by-step Solution
Detailed explanation
We find that each element of new data is 2 times of each element in old data.
Variance of old data \(=23.33\)
\(\therefore\) variance of new data \(=(23.33)(2)^2=93.32\)
Variance of old data \(=23.33\)
\(\therefore\) variance of new data \(=(23.33)(2)^2=93.32\)
