3. QA specialist is interested in comparing the defect rates of tablets produced on two tablet presses TP-1 and TP-2. The data is below: TP-1: Out of 600 tablets tested, 74 have minor defects. TP-2: Out of 200 tablets tested, 19 have minor defects. Test whether the difference between the proportions of defects in the two groups is significant at an alpha level of .05. (a) What are the null and alternative hypotheses? (b) Draw the picture of the distribution of the test statistic (under HO). Include critical value(s) and region(s) of rejection. (c) What is the calculated (computed) value of the test statistic? (d) What is your conclusion
