5. Your firm produces car oil-pan gaskets. The machine used typically produces 98% (.98) that are good, and 2% (.02) that are defective. Your quality control representative takes 400 samples per day. Today, the percentage of "good" gaskets is 97.5% (.975). His instructions are to close the plant down if his quality control test shows that the default rate is more than 2% with a significance level of 10%. If there is not evidence at that significance level he is to let the plant continue operations. Do the hypothesis test to determine if he should shut the plant down.
