Asked by Rebecca

A company manufactures calculators in batches of 64 and there is a 5% rate of defects. What is the standard deviation for the number of defects per batch?
Answered by MathGuru
Standard deviation:

sd = √npq = √(64)(.05)(.95) = ?

Note: q = 1 - p


I'll let you finish the calculation.
