When dragons on the fictional planet Pern lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 31% of the eggs are yellow, and the rest green. Next spring the lead scientist has permission to randomly select 57 of the dragon eggs to incubate. Consider all the possible samples of 57 dragon eggs. Round answers to 4 decimal places. a) Compute the mean number of yellow eggs in samples of 57 eggs? (that is the same as asking for the expected value of the number of yellow eggs)mean = b) Compute the standard deviation in the number of yellow eggs in samples of size 57?standard deviation = c) Compute the variance in the number of yellow eggs in samples of size 57?variance =
