Assume that x is a random variable in a probability distribution with mean μ and standard deviation σ. Find expressions for the mean and standard deviation if every value of x is modified by first being multiplied by 4, then increased by 5.

Find the mean, μ, for the binomial distribution which has the stated values of n and p. Round answer to the nearest tenth.

n = 676; p = 0.7

Use the given values of n and p to find the minimum usual value μ - 2σ and the maximum usual value μ + 2σ. Round your answer to the nearest hundredth unless otherwise noted.
