Using a chi-square goodness-of-fit test, you can decide, with some degree of certainty, w hether a variable is normally distributed In all chi-square tests for normality, the null and alternative hypotheses are as follows H_0: The test scores have a normal distribution. H_a: The test scores do not have a normal distribution. a. Find the expected frequencies.
