In a particular chi-square goodness-of-fit test, there are eight categories and 625 observations. Use the 0.02 significance level. How many degrees of freedom are there? What is the critical value of chi-square?
Added by William A.
Step 1
Determine the degrees of freedom: The degrees of freedom for a chi-square goodness-of-fit test is calculated as the number of categories minus 1. In this case, there are 8 categories, so the degrees of freedom is 8 - 1 = 7. Show more…
