A study was conducted to compare two treatment methods for smokers who wish to stop smoking. Using the Chi-squared Goodness-of-fit test with 5% level of significance, determine whether the data suggests that the two treatments are equally effective in helping smokers stop smoking. The 300 smokers were divided between the two methods, with the following results: TREATMENTS STOPPED SMOKING SMOKE LESS SMOKE THE SAME ROW TOTAL Treatment A 44 38 68 150 Treatment B 33 42 75 150 COLUMN TOTAL 77 80 1 43 300
