QUESTION 7 Select all choices that apply to the p-value A large p-value indicates that we should reject the null hypothesis The probability of making a Type I error O The probability of obtaining a test statistic at least as extreme as the one we obtained, under the alternative hypothesis O The probability of obtaining a test statistic less extreme than the one we obtained, under the null hypothesis A small p-value indicates that we should reject the null hypothesis The probability of obtaining a test statistic at least as extreme as the one we obtained, under the null hypothesis QUESTION 8 The significance level of a test is O Specified before we carry out the test O The probability of rejecting the null hypothesis, given that it is true O A threshold for how rare our outcome must be before we call it evidence against the null hypothesis O All of the aboveQuestion 3 - / 10 is a statistic and an estimator of the parameter and s is a statistic and an estimator of the parameter : 1 H, O 2 p, 02 3 H, Z 4 H, 02 Question 4 - / 10 If the conjecture of a proposed mean, compared to the population mean, results in a probability less than 80%, you would accept the conjecture.
