Mean or Expected Value and Standard Deviation | Introduction to S…
The population of z-scores is normally distributed with a mean of 0 and a standard deviation of 1, so these test results meet the requirements of a standard normal distribution. A randomly selected adult undergoes a bone density test. Find the probability that the result is a reading less than 1.27.

Use the mean and standard deviation to give an interval that is very likely, say 95% chance, to cover the number rats that would actually die. (3 pts.) E(X) = mean of X = np = 100(.20) = 20 rats. SD(X) = standard deviation of X = = rats. When n is “large” the binomial probability distribution is well approximated by a normal distribution.
