Unformatted text preview: This graph is similar to the first one we did; however, the first graph differed slightly because is was equally likely to be above the average number than below it. In this graph, with 1 being about average, it is relatively likely to get a 2 or 3, but very unlikely to get a 5 or 6. The first graph has more of a normal parabolic shape, while this graph steeply increases and then declines in probability. It is much more likely to do worse than 3 correct than to get a 3 or 4. There is a small chance (about 1 in 4) of getting a respectable grade (3 or 4) by guessing. Personally, I would rather study. d) With a 50 question test, the graph above shows that a score between 10 and 15 right would be the average for someone who guesses on all of them. It seems to be nearly impossible to get more than half right, yet it is still likely to get very few correct....
