How do I determine? the χ2 test? statistic, the degrees of? freedom, the critical value using α=0.05?, and? test the hypothesis at the α=0.05 level of significance?
H0?: pA= pB = pC = pD = 4
H1?: At least one of the proportions is different from the others.
Outcome A B C D
Observed 101 101 98 100
Expected 100 100 100 100
