Assume that the probability of a being born with Genetic Condition B is p=1/5. A study looks at a random sample of 971 volunteers. Find the most likely number of the 971 volunteers to have Genetic Condition B. (Round answer to one decimal place.) μ =  Let X represent the number of volunteers (out of 971) who have Genetic Condition B. Find the standard deviation for the probability distribution of X. (Round answer to two decimal places.) σ =  Use the range rule of thumb to find the minimum usual value μ–2σ and the maximum usual value μ+2σ. Enter answer as an interval using square-brackets only with whole numbers. usual values =
