Answer
NL $0.00005, 0.007$
AL $0.00005, 0.007$
The variance and standard deviation for each league are the same.
Work Step by Step
Find midpoints for each class limits, use formula for the group data calculations.
NL
variance 0.00005 (use formula)
standard deviation 0.007 (take square root of variance)
AL
variance 0.00005 (use formula)
standard deviation 0.007 (take square root of variance)
The variance and standard deviation for each league are the same.
