The question is:
A recipe for a batch of 3 dozen chocolate chip cookies calls for 3 cups
of flour 1 cup of suger and 2 cups of chocolate chips how much of each
ingredient should be used to make 2 dozen cookies?
find ratio
for 3 dozen batches, you need 3 cups of flour
so dozen of batches=number of cups of flour
then 3 dozen batches is 1 cup of sugar
so every dozen batches is 1/3 cup sugar
then 3 dozen batches is 2 cups choc chips
so every dozen is 2/3 cups choc chips
for 2 batches
that is 2 cup of flour
2/3 cup of sugar
and 4/3 cup chocolate chips
Given:
Sample proportion = 85% = 0.85.
Confidence level (CL) = 90%.
Confidence interval (CI)

We want the confidence interval to be 5% or 0.05. Therefore

Because this number is less than 1, a default sample size of 30 (for the normal distribution) is recommended.
