Researchers believe that students who study from a screen (e.g., phone, computer) have different grades than students who study from physical pages (e.g., notes). To test this hypothesis, one professor identifies a sample of n = 16 students who study from a screen. They had an average score of M = 72.5 on the final exam. The average for the population of students for the final exam is Mu = 77, σ = 8 and forms a normal distribution. Based on this sample, does the professor have enough evidence to support the researcher’s belief at an α = .05 level? The researcher will use a one-sample z-test. All assumptions have been met
