In what way are the chi-square and normal distributions related?

Question 2

Using the chi-square distribution, along with sample data and frequency counts, what will we be able to examine?

Answer to Question 1

The chi-square distribution is skewed positively, but as its degrees of freedom increase, it approaches the shape of the normal distribution.

Answer to Question 2

We will be able to examine: 1) whether a sample could have come from a given type of population distribution. 2) whether two nominal variables could be independent of each other. 3) whether two or more independent samples could have the same population proportion.
