The shell of the land snail Limocolaria martensiana has two possible colors forms: streaked and pallid. In certain population of these snails, 60% of individuals have streaked shells. Assume that a random sample of 10 snails is to be selected from this population.
Illustrate out Y as the number of streaked-shelled snails in the sample of 10 snails and employ the Y variable in probability notation to determine the probability that the percentage of streaked-shelled snails in the sample will be those requested in problems.
What is the mean number of streaked-shelled snails?
What is the standard deviation of the number of streaked-shelled snails?
Find the typical range of the number of streaked-shelled snails drawn from a random draw of 10 snails expressed as the 1st SD window.
