Check whether the binomial approximation is acceptable in each of the following hypergeometric situations. Check the accuracy of your approximation by using Excel to find the actual hypergeometric probability. (Round "n/N" answers to 2 decimal places and other answers to 4 decimal places.) a. N= 100, n= 4, s= 50, PIX = 3) b. N= 200, n= 13, s = 75, PIX = 3) c. N= 160, n= 13, s= 19, PIX= 2)...

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities More than a decade ago, high levels of lead in the blood put 80 % of children at risk. A concerted effort was made to remove lead from the environment. Now, suppose only 13% of children in the United States are at risk of high blood-lead levels. (a) In a random sample of...

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. It is estimated that 3.6% of the general population will live past their 90th birthday. In a graduating class of 748 high school seniors, find the following probabilities. (Roum your answers to four decimal places.) (a) 15 or more will live beyond their 90th birthday (b) 30 or more will live beyond their...

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. Ocean fishing for billfish is very popular in the Cozumel region of Mexico. In the Cozumel region about 43% of strikes (while trolling) resulted in a catch. Suppose that on a given day a fleet of fishing boats got a total of 30 strikes. Find the following probabilities. (Round your answers to four...

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. Ocean fishing for billfish is very popular in the Cozumel region of Mexico. In the Cozumel region about 45% of strikes (while trolling) resulted in a catch.
