Consider taking a sample of size 10 from the snail population in Exercise 3.6.5.
(a) What is the mean number of streaked-shelled snails?
(b) What is the standard deviation of the number of streaked-shelled snails?
Exercise 3.6.5
The shell of the land snail Limocolaria martensiana has two possible color forms: streaked and pallid. In a certain population of these snails, 60% of the individuals have streaked shells. Suppose that a random sample of 10 snails is to be chosen from this population.
