1. The weights of deer in a national park are normally distributed with a mean of 65 kilograms and a standard deviation of 8.4 kilograms. a) What is the probability that an individual deer selected at random and weighed will weigh more than 67 kilograms? b) What is the probability that 31 deer chosen at random and weighed will have a mean weight more than 67 kilograms? c) What is the probability that 31 deer chosen at randon and weighed will have a mean weight between 59 and 67 kilograms? 2, Find z such that 6% of the area under the standard normal curve lies to the right of z.
