Big Chip cookie at her bakery. She randomly selects a sample of 47
cookies and finds that the number of chocolate chips per cookie in
the sample has a mean of 45. Assume the population standard

number of chocolate chips per cookie for Big Chip cookies? Assume
the data is from a normally distributed population. Round answers
to 2 decimal places where possible.
