True or False. A P-value represents the chance of obtaining a result at least as extreme as our test (a) statistic when the null hypothesis is false. (b) When you reject a null hypothesis that is, in fact, true, you have committed a Type II error. (c) you can view this as an i.i.d. random sample taken freH population of all Hs and Ts that coin can possibly flip. When you flip a coin 50 times, recording whether you got "heads" or "tails" on each flip, When your P-value is 0.213, you will reject the null hypothesis at the significance level (d) a = 0.05. (e) A statistically significant result is not always of practical importance. As you take steps to decrease the chance of Type I error, you correspondingly increase (f) the chance of Type II error.
