Find the probability that a z-score randomly selected from the normal distribution meets the given condition. The Z-score is between -1.5 and 2.5. 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,...
