Question

If the weight (in grams) of cereal in a box of lucky charms is n(479,4), what is the probability that the box will contain less than the advertised weight of 464 gm

Answer 1

about 8.8×10⁻⁵

Explanation:

This probability is best found using a probability calculator of some sort. The z-score is ...

... (464-479)/4 = -3.75

You will have to search a bit to find a probability table that lists probability values for z-scores beyond ±3.00.
