Which lies wholly within the interval, so it is safe to assume that is approximately normally distributed.
Clearly the proportion of the population with the special characteristic is the proportion of the numerical population that are ones; in symbols, But of course the sum of all the zeros and ones is simply the number of ones, so the mean μ of the numerical population is. In each case decide whether or not the sample size is large enough to assume that the sample proportion is normally distributed. D. Sam will take 104 flights next year. Find the indicated probabilities. Suppose that 29% of all residents of a community favor annexation by a nearby municipality. To learn more about the binomial distribution, you can take a look at.
The Central Limit Theorem has an analogue for the population proportion To see how, imagine that every element of the population that has the characteristic of interest is labeled with a 1, and that every element that does not is labeled with a 0. He knows that five years ago, 38% of all passenger vehicles in operation were at least ten years old. The information given is that p = 0.
