When dragons on planet Pern lay eggs, the eggs are either green or yellow. The biologists haveobserved over the years that 37% of the eggs are yellow, and the rest green. Next spring the leadscientist has permission to randomly select 67 of the dragon eggs to incubate. Consider all thepossible samples of 67 dragon eggs.What is the mean number of yellow eggs in samples of 67 eggs? (that is the same as asking for theexpected value of the number of yellow eggs)(Give answer correct to at least one decimal place.)mean =What is the standard deviation in the number of yellow eggs in samples of size 67?(Give answer correct to at least one decimal place.)standard deviation =What is the variance in the number of yellow eggs in samples of size 67?(Remember to calculate the answer using at least 5 decimal places, then give answer correct to at leastone decimal place.)variance =
