This is a Lesson 14problem.

You should write down the mean and standard deviation for this problem.

You might see multiple versions of this problem, but mu and sigma will not change.

***************************************

A certain restaurant in Washington serves the sea bass special on Saturday nights.

Historically,19%of customers order the sea bass.

We expect n = 449 customers every Saturday.

We will model the proportion of customers that order the sea bass special.
