Question 1139055: The breaking strengths of metal spokes in bicycle tires are normally distributed with mean
µ = 23.56 Newtons and standard deviation, σ = 4.55. What proportion of spokes would have
a breaking strength of 14.45 or less? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z<(x-mean)/sd or < (14.45-23.56)/4.55
this is z<-9.11/4.55 or -2
That is a probability of 0.0228
