Answer with Step-by-step explanation:
We are given that a class's test scores are normally distributed with the average score 60.
We know that the curve of a normal distribution is symmetric about its mean.
60-14=46
60+14=74
Hence, the point 46 lies to the left of the mean and 74 lies to the right of mean and the two points have the same function value
(since the graph is symmetric to the left and right of mean i.e. points which are equidistant from the mean have same values)
