1. Suppose we know that the birth weight of babies is normally distributed with mean 3500g and standard deviation 500g. (1) What is the probability that a baby is born that weighs less than 3100g? a. Find the z-score, and construct the standard normal distribution density curve, then shade your seeking area. b. Find the probability. (2) If 25 new born babies are randomly selected, what is the probability that the 25 babies are born that their mean weigh less than 3 100g? a. Find the zscore, and construct the standard normal distribution density curve, then shade your seeking area. b. Find the probability
