A movie based on a best-selling novel was recently released. Six hundred viewers of the movie, 235 of whom had previously read the novel, were asked to rate the quality of the movie. The survey showed that 141 of the novel readers gave the movie a rating of excellent, while 248 of the non-readers gave the movie an excellent rating. b. Can we conclude, on the basis of a hypothesis test about p1 – p2, that the proportion of the non-readers of the novel who thought the movie was excellent is greater than the proportion of readers of the novel who thought the movie was excellent? Use a 0.05 level of significance. (Hint: This is a one-tailed test.) Choices: H0: pNR – pR ≤ 0; z = 2.274 > 1.645; p-value = 0.0815 < .05; reject H0 H0: pNR – pR ≤ 0; z = 2.274 > 1.645; p-value = 0.0115 < .05; accept H0 H0: pNR – pR ≤ 0; z = 2.274 > 1.645; p-value = 0.0115 < .05; reject H0 H0: pNR – pR ≤ 0; z = 3.274 > 1.645; p-value = 0.0115 < .05; reject H0
