Determine whether you can use the normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use the binomial distribution to find the indicated probabilities. A survey of adults in a region found that 52% have encountered fraudulent charges on their credit cards. You randomly select 100 adults in the region. Complete parts (a) through (d) below (a) Find the probability...

A binomial experiment is given. Decide whether you can use the normal distribution to approximate the binomial distribution. If you? can, find the mean and standard deviation. If you? cannot, explain why. A survey of adults found that 90?% read every word or at least enough to understand a contract for buying or selling a home before signing. You ask 14 adults selected at random if he or she reads every word or at least enough to understand a contract...

6. In this question, you are going to study the approximation to binomial probabilities using the nor mal distribution. The binomial distribution is discrete while the normal distribution is continuous Therefore, we would expect some issues with approximating the binomial with the normal. (a) (2 points) Suppose X ~ Bin (25,04). Calculate E (N) and Var . (b) (4 points) Use the central lit theorem along with (a) to approximate Pr (X 8). Compare this with your result in #4(a)....
