Goodness of fit Step 1: the null hypothesis will be of the form p1=#, p2=#, ... pk=# Step 3: the test statistic is x2, where Oi is the observed sample frequency for category Step 4: compute the test statistic and P-value Step 5: conclude if there is efficient or not efficient evidence to support the claim 2) An algebra instructor tells his students on the first day of class that 40% will pass, 30% will fail, and 30% will withdraw that semester if historical patterns hold true. The class began with 38 students. Seventeen of the students passed the class, 6 failed, and the rest dropped. At the 0.05 level of significance, test the claim that the instructor made on the first day of class
