In a randomized controlled​ trial, insecticide-treated bednets were tested as a way to reduce malaria. Among 312 infants using​ bednets, developed malaria. Among infants not using​ bednets, developed malaria. Use a significance level to test the claim that the incidence of malaria is lower for infants using bednets. Do the bednets appear to be​ effective? Conduct the hypothesis test by using the results from the given display. Difference​p(1)​p(2) Estimate for​ difference: ​% upper bound for​ difference: Test for difference0 ​(vs ​0): Z ​P-Value What are the null and alternative​ hypotheses?

Identify the​ P-value. nothing ​(Type an integer or decimal rounded to three decimal places as​ needed.) What is the conclusion for this​ test? The​ P-value is ▼ greater than less than the significance level ​, so ▼ fail to reject reject the null hypothesis. There is ▼ insufficient sufficient evidence to support the claim that the incidence of malaria is lower for infants using bednets. The bednets ▼ appear do not appear to be effective.
