The data files `class1.csv` and `class2.csv` provided contain test scores for students in two sections of a Biology course. In Class 1, there are 75 students and in Class 2, there are 50 students. Read in both data files and store them as objects `class1` and `class2`.

(a) Make a sina plot comparing the distribution of test scores between the two sections

(b) Calculate the moment coefficient of skewness for the `class1` and `class2` datasets.

Based on the moment coefficient of skewness, state whether the test scores in each class are skewed the left, skewed to the right, or approximately symmetric.

(c) Calculate the sample kurtosis for each class.

Based on the calculated sample kurtosis, which class has a distribution of test scores whose tails are most similar to the tails of the normal distribution?
