Boxes of Bran Flakes are known to be normally distributed with a mean wieght of 475g and a standard deviation of 10g.
Calculate the probability of a box having a weight exceeding 485g.
Z=(X-mean)/sd
Z=(485-475)/10
Z=10/10
Z=1
Not sure where to go from here.....how do i read the z table?
So therefore the probability would be____?
Calculate the probability that a mean wieght of 16 boxes will exceed 480g
Z=(X-mean)/(sd/√16)
Z=(480-475)/(10/√16)Z=10/(10/4)
Z=10/2.5
Z=4
So therefore probability would be ____?
