Question 1043560: Find the minimum sample size n needing to estimate u for the given values c=0.90 s=7.3 E=2 assume that a preliminary sample has at least 30 members Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Find the minimum sample size n needing to estimate u for the given values c=0.90 s=7.3 E=2 assume that a preliminary sample has at least 30 members
----------
n = [z*s/E]^2
n = [1.645*7.3/2]^2 = 36 or 37 if you round up
