(a) In formulating hypotheses for a statistical test of significance, the null hypothesis is often OA. a statement that the data are all 0. O B. the probability of observing the data you actually obtained OC. a statement of "no effect" or "no difference". O D. 0.05 (b) The P-value of a test of a null hypothesis is O A. the probability the null hypothesis is false. O B. the probability, assuming the null hypothesis is true, that the test statistic will take a value at least as extreme as that actually observed. O C. the probability the null hypothesis is true. O D. the probability, assuming the null hypothesis is false, that the test statistic will take a value at least as extreme as that actually observed. (c) In testing hypotheses, which of the following would be strong evidence against the null hypothesis? O A. Using a large level of significance. OB. Obtaining data with a small P-value. O C. Obtaining data with a large P-value. O D. Using a small level of significance.
