PVC pipe is manufactured with a mean diameter of 2.565 cm and a standard deviaiton of 0.008 cm. Find the probability that a random sample of n=9 sections of pipe will have a sample mean diameter greather than 2.560 cm and less than 2.570 cm.

answer: x

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
