Question

For: "The diameter of optical fibre produced by a manufacturer is known to be normally distributed, with a mean of .502mm and standard deviation of .0025mm. The specification requires that the diameter of the fibre be equal to .5mm (plus or minus) .005mm. What proportion of the manufacturer's production will fail to meet the specification?" : Do you create a normal distribution curve?

Answer 1

its known to be normally distributed, so yeah, id make a curve

Answer 2

Then just find the probability of the outer?

Answer 3

looks like it to me, but thats just a hunch

Answer 4

find zscores and probs for .505; and .495

Answer 5

thank you

Answer 6

i gotta wonder tho since its asks for proportion instead of probability; its basiclly the same steps tho

Answer 7

It's just trying to be complex

Answer 8

:) prolly lol

Answer 9

nah
