Please see the attached file for full problem description.
A machine that manufactures automobile pistons is estimated to produce a defective piston of the time. Suppose that this estimate is correct and that a random sample of pistons produced by this machine is taken.
a. Estimate the number of pistons in the sample that are defective by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable). Do not round your response.
a. Quantify the uncertainty of your estimate by giving the standard deviation of the distribution. Round your response to at least three decimal places.© BrainMass Inc. brainmass.com September 24, 2022, 7:00 pm ad1c9bdddf
The following solution describes the process of finding the mean and standard deviation of defects expected in a sample. A machine is known to produce 3% defects and the sample taken is 80.
