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?

Question

amistre64 · Answer

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

anonymous · Answer

Then just find the probability of the outer?

amistre64 · Answer

looks like it to me, but thats just a hunch

amistre64 · Answer

find zscores and probs for .505; and .495

thank you

amistre64 · Answer

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

anonymous · Answer

It's just trying to be complex
