An assembly line inspector is interested in determining if there is an equal proportion of “Type-A” widgets and “Type-B” widgets. After counting the observed frequency of each widget that actually comes off the assembly line, the inspector computes the frequency that he would expect to come off the assembly line if it is producing an equal number of widgets. 1 What hypothesis test would be most appropriate for answering this research question and why?   2 Is it important to distinguish between one- and two-tailed hypotheses for this test? Explain why/why not.   3 What would the degrees of freedom be?
