Ackerman & goldsmith (2011) found that students who studied text from printed hard copy had better test scores than students who studied text presented on a screen. in a related study, a professor noticed that several students in a large class had purchased the e-book version of the course textbook. for the final exam, the overall average for the entire class was μ = 85, but the n = 10 students who purchased the e-book had a mean of m = 77 with a standard deviation of s = 6. do these data indicate a significant decrease in test scores on the final exam due to the use of a e-book? use a one-tailed test with α = .05.
