Question 3 A machine assembly is developed to produce a range of new material, which are size-coded small, medium and large. The machine assembly is programmed to produce 45.76% small, 29.41% medium and 24.83% large items. A sample of 80 items was taken and the following distribution was observed: size small medium large Frequency 26 43 15 At 1% level of significance, We wish to test if the assembly line needs adjustment? a. Calculate the test statistic (round to 2 decimals) [A] b. Find the critical value [B] c. What is your conclusion? Answer: Since the test statistic is (greater/less) [c] than the critical value, we (do/ don't ) [d] have enough evidence to conclude that all four entrances are used unequally
