The average daily protein consumption of children in school is 30 grams. It is also known that its variance is 64 grams. Under the Normal distribution assumption;
a) since these children are advised not to take less than 18 grams of protein, what is the proportion of children who receive insufficient protein?
b) since it is known that 20% of children receive more protein than recommended, what is the limit for excess protein?

Suppose that the daily consumption of Pepsi in ounces by a high school student is normally distributed with mean = 13.0 ounces and variance = 2.0 ounces. The daily amount consumed is independent of other days except adjacent days where the covariance is -1.0. If the student has two six-packs of 16 ounce Pepsi bottles, what is the probability that some Pepsi remains at the end of two-weeks ?
