Answer: AP English Literature
===========================================================
Explanation:
For the AP English Literature score, we'll have these steps
z = (x - xbar)/sigma
z = (4 - 2.78)/(1.10)
z = 1.109 which is approximate
Repeat for the AP Calculus score
z = (x - xbar)/sigma
z = (4 - 2.68)/(1.55)
z = 0.852 approximately
Even though Jenna got 4's on both exams, she did better relative to her peers on the AP English Literature exam since she got a larger z score.
Side note: The first two rows of each table aren't used at all.
