Hypotheses

For the first investigative question, I hypothesize that the most probable score is 35%, while the least probable score is 100%. In other words, the graph would look like a curve, peaking at 35%. It would ascend to its peak, and then descend the rest of the way (going from left to right).

I think that the chances of getting a passing mark will be very slim. This will depend on the scenario that is examined.

I estimate that the class average will be around 40%, a little higher than my hypothesized most probable score.
