Expert Solution
Step 1
The following steps are involved in the chi-square test of independence.
Part 1:
We first identify the claim and the variables of interest and then state the null and alternate hypothesis as,
H0: The two variables are independent.
H1: The two variables are dependent.
Part 2:
The level of significance, denoted by ∝, is the probability of rejecting the null hypothesis when it is true and is generally taken to be 5%. That is ∝ = 0.05.
