A week before a state election, a random sample of voters from City J and a random sample of voters from City K were taken. Of the 100 voters selected from City J, 65 indicated they were supporting a certain candidate for state senate. Of the 125 voters selected from City K, 75 indicated they were supporting the candidate. Which of the following is the correct test statistic for a two-sample z z -test for a difference in population proportions for the two cities (J minus K) in their support for the candidate? Responses 0.65−0.60(0.65)(0.6)(1100+1125)√ the fraction with numerator 0.65 minus 0.60 and denominator, the square root of 0.65 times 0.6 times, open parenthesis, the fraction 1 over 100 plus the fraction 1 over 125, close parenthesis, end root 0.65−0.60(0.62)(0.38)(1100+1125)√ the fraction with numerator 0.65 minus 0.60 and denominator, the square root of 0.62 times 0.38 times, open parenthesis, the fraction 1 over 100 plus the fraction 1 over 125, close parenthesis, end root 0.65−0.60(0.62)(0.38)(1100+125)√ the fraction with numerator 0.65 minus 0.60 and denominator, the square root of 0.62 times 0.38 times, open parenthesis, the fraction 1 over 100 plus 125, close parenthesis, end root 65−75(0.65)(0.60)(1100+1125)√ the fraction with numerator 65 minus 75 and denominator, the square root of 0.65 times 0.60 times, open parenthesis, the fraction 1 over 100 plus the fraction 1 over 125, close parenthesis, end root 65−750.62100+0.38125√
