Write the hypotheses for testing whether the proportion of women correctly screened with Method A is different from the proportion of women correctly screened with Method B. H0: pMethod A pMethod B H1: pMethod A pMethod B ii. Using the given calculator output above and α = 0.05, state the appropriate decision about the null hypothesis and conclusion.
