Let the random variable X be the weight of a box of Cheerios cereal. This variable has a Normal distribution with mean=18 ounces and standard deviation= 0.3 ounces.

a) Draw the Normal density curve for X, marking the mean and the 6 values that demonstrate the

68, 95, 99.7 rule.

b.)What percent of the boxes have a weight between 17.4 and 18.6 ounces?

c)What percent of the boxes have a weight between 17.1 and 18.9 ounces?

d)What is the probability that a randomly selected box of Cheerios has a weight equal to 18.6 ounces?

e)What is the probability that a randomly selected box of Cheerios weighs below 17.1 ounces?

f)What is the probability that a randomly selected box of Cheerios has a weight between 17.7 and 18 ounces?
