Answer to Question #233007 in Statistics and Probability for Winsome Ogidi

Question

Sir please how do you get your p value and z did you use a chi square table and how did you get the values it’s really confusing

Answer 1

Solution:

If your test statistic is positive, first find the probability that Z is greater than your test statistic (look up your test statistic on the Z-table, find its corresponding probability, and subtract it from one). Then double this result to get the p-value.

z value comes from N(0,1) distribution table. Chi square table gives us critical value with (d) degrees of freedom.
