Answer 1

Question 1

I want to know if the percentage of traffic accidents changes by day for a given week in Ephraim. What type of test would I do?

Answer:

Chi squared GOF test

Here, we have to check whether the sample data follow the given percentages or not. IN other words, we have to check whether the given data fits the given proportions or not. So, we need to use chi square test for goodness of fit.

Question 2

I am interested in studying if College Major is related to living location preference (West Coast, East Coast, Non-coastal)

What type of test should I do after I gather students’ data?

Answer:

Chi Squared Test for independence

Explanation:

For the given scenario, we are given two categorical variables such as college major and location preference. So, for checking the independence between these two categorical variables we need to use the Chi-square test for independence between two categorical variables.
