Find the variance within the samples i.e. ?
(Roundoff the answer to two decimal digits)
Homework Answers
Answer #1
There are 3 samples here, we first compute the mean for each sample here as:
Therefore, the variation within samples now is computed here as:
Therefore 401.33 is the required variance here.
