A researcher used a sample of n = 60 individuals to determine whether there are any preferences among four brands of pizza. If the data are evaluated with a chi-square test for goodness of fit using α = .05, what is the critical value?
Homework Answers
Solution :
Given that ,
There are any preferences among four brands of pizza.
df = 4 - 1 = 3
P(
3
> 7.815) = 0.05
Critical value = 7.815
