Homework Help: Statistics

Posted by Jason L on Monday, February 26, 2007 at 3:24pm.

A paper manufacturer claims that fewer than 1 in 100 of its reels (2 ton rolls) of paper is flawed. A customer has just received a large shipment of these reels and proceeds to check a random sample of 600 of them for flaws. Of this sample, 14 reels are found to be flawed. What is the probability of finding at least 14 flawed reels in this sample?
Part 2

What would u conclude about the manufacturers claim?

The claim is probably true?
The claim may be false?
The claim is probably false?

Since the probability is very small of finding at least 14 reels in the sample (see previous post), you can conclude that the claim is probably true.
