(1 point) (For the following question, you may use the "hand calculations" described in lecture. You must use at least four decimal places for all intermediate calculations and your final answer. If you use R prop.test(), remember to convert the X2 value to a Z value for your answer!) Independent random samples, each containing 80 observations, were selected from two populations. The samples from populations 1 and 2 produced 39 and 29 successes, respectively. Test Ho : (P1 – P2)...
