a. What are the null and alternative hypotheses? Let the infants using bednets be sample 1 and let the infants not using bednets be sample 2. Choose the correct hypotheses below. A. Upper H 0: p 1greater than or equalsp 2 Upper H 1: p 1less thanp 2 B. Upper H 0: p 1equalsp 2 Upper H 1: p 1not equalsp 2 C. Upper H 0: p 1equalsp 2 Upper H 1: p 1greater thanp 2 D. Upper H 0: p 1equalsp 2 Upper H 1: p 1less thanp 2 E. Upper H 0: p 1less than or equalsp 2 Upper H 1: p 1greater thanp 2 F. Upper H 0: p 1not equalsp 2 Upper H 1: p 1equalsp 2 Part 2 Identify the test statistic. negative 2.09 (Round to two decimal places as needed.) Part 3 Identify the P-value. 0.018 (Round to three decimal places as needed.) Part 4 What is the conclusion for this test? Since the P-value is less than the significance level alpha, reject the null hypothesis. Part 5 b. Let the infants using bednets be sample 1 and let the infants not using bednets be sample 2. Use a 0.01 significance level to construct a confidence interval. enter your response hereless thanleft parenthesis p 1 minus p 2 right parenthesisless than enter your response here (Round to three decimal places as needed.) Part 6 What is the conclusion for the confidence interval? Since the confidence interval contains does not contain zero, there does not appear appears to be a difference between the proportions. Part 7 c. Based on the results, do the bednets appear to be effective? According
