Which option fits type II error the best? O Probability of correctly rejecting the null hypothesis "Probability of rejecting the null, if the null is true" "Probability of retaining the null, if the nullis false." O "Probability of retaining the null, when it s false" QUESTION 2 The appropriate test for a study of people tested before and after they are given a drug is: z-test independent-samples t-test paired-samples t-test one-way...

α is the probability of a Type I error, which occurs when we accept the alternative H1 when the null hypothesis Ho is true. True False A Type II error occurs when when a false null hypothesis is rejected. True False If a null hypothesis is rejected at the 5% significance level but not at the 1% significance level, then the p-value of the test is less than 1%. True False The power of a test is the probability of...

Question 33 1 pts If the significance level for a hypothesis test is 0.01 and the p-value for the test ends up being 0.0034, after forming the appropriate conclusion based on the p-value, which possible error could have be committed, type I or type II. Since we did not reject the null, we might have committed a type one error. O Since we did not reject the null, we might have committed a type two error. Since...
