A study reports that students studying from electronic screens tend to have different quiz
scores than students who study from printed pages. To test this finding, a professor
identifies a sample of n = 25 students who used the electronic version of the textbook and
determines that this sample had an average score of M = 75 on the quiz. The quiz scores
for the general population of students taking the course averaged µ = 80 with a standard
deviation of σ =7 with a roughly
sample to determine whether students studying from electronic screens are significantly
different from those for the general population.
a. Assuming a one-tailed test where the professor thinks the electronic version of
the textbook increases quiz scores, state the null and alternative hypotheses. Present
this in computational form (i.e., using notation) and also underneath each write out
what they mean.
