Question

Pauline sits near the snacks in the office. There are 555 flavors of chocolate, and she wonders if some flavors get chosen more than others. She plans to record how often each flavor gets chosen in a sample of selections to carry out a \chi^2χ 2 \chi, squared goodness-of-fit test on the resulting data.

Answer 1

The flavor of chocolate is an illustration of a simple random distribution

Pauline's expects each snack to be selected at least 5 times, and she takes a random sample of selections

How to determine the true statements about the chi squared goodness of fit test

The number of flavors of chocolate is given as:

n = 5

For a chi squared goodness of fit test, the following must be true:

• The expected value of the number of sample observations is at least 5.
• The sampling distribution must be a simple random

The above highlights mean that true statements are:

Pauline's expects each snack to be selected at least 5 times, and she takes a random sample of selections
