" but instead "how big is the e ect? " t address ths second quest on, use the inf ation given below to fi da % confidence inte a for the difference in propor ons where epresents e op tion of tems correctly recalled by all students who study using a sclf quiz method and p2 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 chrenoes is also about 0.07 the proportion of tems correctly recalled was 0.15 or the reading-study group and 0.42 for the self-quiz group. round your answers to two decimal places.
