Answer:
85
Step-by-step explanation:
A z-score of 1.25 means that the actual exam score is 1.25 standard deviations above the mean, and therefore the exam score we are looking for is: mean + 1.25 * SD = 75 + 1.25 * 8 = 85
3/2^2 or 0.75 because you have to take the middle value (3), divide it in half, then square it. That would be 0.75.
