The production department of a newspaper has embarked upon a quality-improve Solution you are given mean=1.005 and deviation as 0.10 apply normal distribution z=(x- mean)/deviation see the statistical tables under normal distribution and find the solutions a) u need p(,0.95) substitute x=.95 second u need between 0.95 and 1 substitute 1 first find the value and then .95 is known from above [note if u have a negative value of z then the value will be like if its f(-z)=1-f(z)] and similarly.
