Sample Size E. coli Prevalence Organic 260 3 Conventional 510 20 Is there a significant difference in the proportion of E. coli in organic vs. conventionally grown produce? Test at a = 0.10. (Let d = Organic - Conventional.) (a) Formulate the hypotheses. $H_0: p_1 - p_2 = 0$ $H_a: p_1 - p_2 \neq 0$ (b) What is the value of the test statistic? (Round your answer to three decimal places.) (c) What is the p-value? (Round your answer to three decimal places.) p-value = (d) What is your conclusion? Reject $H_0$. We can conclude that there is a significant difference in the proportion of E. coli in organic vs. conventional produce. Reject $H_0$. We cannot conclude that there is a significant difference in the proportion of E. coli in organic vs. conventional produce. Do not reject $H_0$. We cannot conclude that there is a significant difference in the proportion of E. coli in organic vs. conventional produce. Do not reject $H_0$.
