A local deli chain makes a signature sandwich. Suppose the measures of fat grams in the
signature sandwiches are normally distributed with mean μ = 16 grams and standard
deviation σ = 1.5 grams. Find the probability that a randomly selected signature sandwich
will have no more than 19 fat grams.
A plumbing company has found that the length of time, in minutes, for installing a bathtub is
normally distributed with mean μ = 160 minutes and standard deviation σ = 25 minutes.

The weights of newborn baby girls born at a local hospital are normally distributed with mean
μ = 100 ounces and standard deviation σ = 8 ounces. If a newborn baby girl born at the
hospital is randomly selected, what is the probability that the child's weight will be at least 88
ounces?
