1) A supplier ships a lot of 5000 connectors. A sample of 500 is selected at random, without replacement. If the lot contains 400 defective connectors, use normal approximation to determine the probability that there are 50 defective connectors in the sample.
A company makes auto batteries. They claim that 81% of their LL70 batteries are good for 70 months or longer. Assume that this claim is true. Let p^ be the proportion in a random sample of 90 such batteries that are good for 70 months or more.
In manufacturing processes, it is of interest to know with confidence the proportion of defective parts. Suppose that we want to be reasonably certain that less than 4 % of a company's widgets are defective. To test this, we obtain a random sample of 250 widgets from a large batch. Each of the 250 widgets is tested for defects, and 6 are determined to be defective,based upon the manufacturers standards.using a= 0.01, is this evidence that less than 4% of the company's widgets are defective? State the hypothesis, list and check the conditions, calculate the test statistic, find the p-value, and make a conclusion in a complete sentence related to the scenario.
