4] From the histograms, one could see how the data quantity affects the overall shape and width. As more data is accumulated, the histogram becomes wider and resembles a normal curve better, as opposed to the histograms with few data points. The difference between the incidences of heart attack seen in the drug and control group are hardly noticeable; both have the exact same mode (2) and the number of occurrences in the mode (21). In the Drug Group, the difference seems to be most obvious, where the frequency was significantly higher at 2, which marks the approximate mean. Yes, the Drug Group would be the case in which the highest level of confidence of a difference in the number of heart attacks could be derived; even though both cases had the same occurrences, the peak of the curve in the Drug Group is more dramatic relative to the other values not included in the interval of the crest.
