The weight of a loaf of bakery bread at the grocery store follows a Normal distribution with a mean of μ = 12 ounces and a standard deviation of σ = 1 ounce. Suppose we pick four loaves at random from the bin andfind their total weight, W. Which of the following statements describes the random variable W?O The random variable W is binomial, with a mean of 48 ounces and a standard deviation of two ounces.O The random variable W is binomial, with a mean of 12 ounces and a standard deviation of two ounces.O The random variable W is Normal, with a mean of 12 ounces and a standard deviation of one ounce.O The random variable W is Normal, with a mean of 48 ounces and a standard deviation of two ounces.O The random variable W is Normal, with a mean of 48 ounces and a standard deviation of four ounces.
