Manufacturer Sample
From 80,000 jars produeced, a manufacturer samples 1,200 and finds 7 of those defective.?
Estimate the total number of defective jars.
Can you explain how you do it?
& Please show the work.
produced****
I would cross multiply
x (def jars) 7 defective jars
------------------ = ___________________
80,000 jars produced 1200 sampled
7(80000) = 1200 x
so to solve for x you would multiply 7 and 80000 and divide by 1200 giving you 466.67 estimating to 467 defeftive jars.
