Step-by-step explanation: save time on your test by cheating yourself of knowledge
Let X be a random variable representing the weight of a pack of cookies.
P(X < 250) = P(z < (250 - 255)/2.5) = P(z < -5/2.5) = P(z < -2) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275 = 2.3%
Therefore, we conclude that about 2.3% of the packs weighed less than 250 grams.
