Weinstein, McDermott, and Roediger (2010) report that students who were given questions to be answered while studying new material had better scores when tested on the material compared to students who were simply given an opportunity to reread the material. In a similar study, an instructor in a large psychology class gave one group of students questions to be answered while studying for the final exam. The overall average for the exam was u = 73.4, but the n = 16 students who answered questions had a mean of M = 78.3 with a standard deviation of s = 8.4. For this study, did answering questions while studying produce significantly higher exam scores? Use a one-tailed test with a = .01 and the Distributions tool to help. (Round your answers to three decimal places, when needed.)

Weinstein, McDermott, and Roediger (2010) report that students who were given questions to be answered while studying new material had better
scores when tested on the material compared to students who were simply given an opportunity to reread the material. In a similar study, an
instructor in a large psychology class gave one group of students questions to be answered while studying for the final exam. The overall average for
the exam was u =
73.4, but the n = 16 students who answered questions had a mean of M = 78.3 with a standard deviation of s = 8.4. For this
study, did answering questions while studying produce significantly higher exam scores? Use a one-tailed test with a = .01 and the Distributions tool
to help. (Round your answers to three decimal places, when needed.)
