1. State the critical value of the chi-square random variable for this test of independence of catagories.
2. Calculate the value of the test statistic.
3. what is the conclusion for the test?
<br>I will explain part 3 right now.
<br>When you calculate the test statistic, you have to see what that value is. IF the value that you calculate is LESS then 21.03, then you have to conclude that there is NO RELATIONSHIP between the location and the program of study.
<br>On the other hand, if you test statistic is HIGHER then 21.03, then you have to conclude that there IS A RELATIONSHIP between the location and the program of study.
<br>2) to calculate the test stat.
<br>Chi sq. is a test that compairs the actual ...
