If the probability of observing heads upon spinning the penny is p = 0.30, and three students got together, where they would each spin a penny and record the number X of heads out of the three spins. They repeated this experiment n = 200 times, observing 0, 1, 2, and 3 heads 57, 95, 38, and 10 times, respectively. How do you give limits for the p-value of this test? In addition, out of the 600 spins, how would you calculate the number of heads occurring and then get a 95% confidence interval for p?
