A professor is teaching two sections of a Calculus course, section A and section B. Assume that the test scores are normally distributed.
On the midterm, Kelvin in section A scored an 82. The mean of section A was 76 and the standard deviation of the section was 5.
Laila, in section B, also scored an 82 but the mean of section B was 75 with a standard deviation of 4.
The results from this problem will be used on the next problem so it is a good idea to write them down but you may return to this problem as well.
Find the z-score for Kelvin and the z-score for Laila for the midterm of this Calculus course.
OA. Kelvin: z=-1.2 and Laila z = -1.75
OB. Kelvin: z=1.2 and Laila z=-1.75
OC. Kelvin z = 1.2 and Laila z=1.75
OD. Kelvin: z=-1.2 and Laila: z = 1.75
