Question

For each of your 5 samples of 12 flips, use the binomial distribution to test the null hypothesis that the coin is fair, using α= .05 (two-tailed). (The alternative hypothesis is that the coin is notfair.) For each sample, calculate the p value (the probability of getting the number of heads you did or a more extreme number of heads (“two-tailed”) purely by chance). Show your work and organize the data into a small table. For each sample indicate the number of heads out of 12, the p value, your decision about the null hypothesis, and the explicit reason for your decision, in terms of the decision rule.
