We can assume normal here. Tossing a coin repeatedly and looking for heads is a simple example of Bernoulli trials: there are two possible outcomes (success and failure) on each toss, the probability of success is constant, and the trials are independent.
As was the case for two proportions, determining the standard error for the difference between two group means requires adding variances, and that's legitimate only if we feel comfortable with the Independent Groups Assumption. In addition, we need to be able to find the standard error for the difference of two proportions. Some students are taking AP Statistics after already having completed Calculus, and according to her, others "sneak in" by getting through Algebra II. Many students observed that this amount of rainfall was about one standard deviation below average and then called upon the 68-95-99.
