Answer:
The mean of W is 55 ounces.
The standard deviation of W is 4.33 ounces.
Step-by-step explanation:
Let X: weight of a red delicious apple, and B: the weight of the box and packing material.
The distribution that will represent W: the total weight of the packaged 5 randomly selected apples will be also normally distributed.
Applying the property of the mean:
, the mean of W will be:

Applying the property of the variance:
, the variance of W will be:

The mean standard deviation of W will be the squared root of V(W):

The mean of W is 55 ounces.
The standard deviation of W is 4.33 ounces.
