Not at all, we cannot say because we do not have enough data.

Step-by-step explanation:

The fact is we only have the score of one individual out of a population. This sample is not enough to aid in drawing a conclusion. Basically, the more samples we get from the population, the closer to accuracy we get. Therefore, we will need more scores from the geometry test to predict more accurately than with just the score of Louise.

Moreover, Louise is taking an advanced calculus course, so we can infer that she is quite apt when it comes to Mathematics.

Other students may have performed well and they also may not have, but we can not tell with just the score of an individual.
