Assume that M&M weight is normally distributed.Use excel for all of this.

1. A bag is filled with 100 red M&Ms, calculate the mass as a mean and standard deviation. Then the same for 100 blue M&Ms.
2. What is the probability that a single red M&M weighs more than a blue M&M?
3. What is the probability that 100 red M&Ms weighs more than 100 blue M&Ms?
4. If you choose a brown M&M at random, what is the probability that it weighs less than 0.8 g?
5. If you picked 10 brown M&Ms at random and averaged their masses, what is the probability that the average mass is less than 0.8 g?
