The random variable W is Normal, with a mean of 48 ounces and a standard deviation of four ounces.

By their properties, mean of μ(4x) = 4 * μ(x) and a standard deviation of σ(4x) = 4 * σ(x).
So the distribution of weight of four loaves of bread, W, still follows a Normal Distribution with a mean of 4*12 = 48 ounces and a standard deviation of 4*1 = 4 ounces.
