We have found that students who study by giving themselves quizzes recall a greater proportion of words than students who study by reading. Also, we see that there is an effect, but often the question of interest is not ββIs there an effect?" but instead ββHow big is the effect?" To address this second question, use the information given below to find a confidence interval for the difference in proportions , where represents the proportion of items correctly recalled by all students who study using a self-quiz method and represents the proportion of items correctly recalled by all students who study using a reading-only approach. Assume that the standard error for a bootstrap distribution of such differences is also about 0.07. The proportion of items correctly recalled was 0.15 for the reading-study group and 0.42 for the self-quiz group. Round your answers to two decimal places.
