Question: One or more specific minor birth defects occur with probability
One or more specific, minor birth defects occur with probability .0001 (that is, 1 in 10,000 births). If 20,000 babies are born in a given geographic area in a given year, can we calculate the probability of observing at least one of the minor defects using the binomial or normal approximation to the binomial? Explain.
Answer to relevant QuestionsThe sample mean to be calculated from a random sample of size n = 4 from a population that consists of eight measurements (2, 6, 9, 12, 25, 29, 39, 50). Find the sampling distribution of y. Refer to Exercise 4.108. To evaluate how accurately the sample mean y estimates the population mean m, we need to know the chance of obtaining a value of y that is far from μ. Suppose it is important that the sample mean y ...A credit union takes a sample of four mortgages each month to survey the homeowners’ satisfaction with the credit union’s servicing of their mortgage.
