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 a. Develop an interval estimate of the difference between the proportions of the two populations (readers vs non-readers), using a 0.05 level of significance, as the basis for your decision.

b. Can we conclude, that the proportion of the non-readers of the novel who thought the movie
was excellent is different than the proportion of readers of the novel who thought the movie
was excellent? (Hint: without the use of a hypothesis test.)
