Zoologists estimate that a randomly selected baby giraffe has a 32% chance of surviving to adulthood. Assume this estimate is correct. Suppose researchers select 100 baby giraffes at random to tag and monitor. X, the number of these giraffes that survive to adulthood, is a binomial random variable. Calculate the mean and standard deviation of X. Round to 4 decimal places, when necessary.
