When conducting a hypothesis test (or test of significance), select all the true statement. assume the alternative hypothesis is true. significance level is selected before collecting data. None of these (can be more than one answer) Select the correct answer for the blank of each of the following statements. (i) A smaller significance level makes it (choose one: more difficult, easier)    to reject the null hypothesis. (ii) The p-value of a two-tail (or two-side) test is  (choose one: twice(double), half of, same as)    the p-value of a one-tail (or one-side) test if everything else stays the same. (iii) It is   (choose one: possible, impossible)  to make both type I error and type II error in one hypothesis test at the same time. (iv) Statistical significance (choose one: implies, does not imply)     practical significance.

If the null hypothesis is false, you cannot make which kind of error? Type I Type II

Need help with this question. Thank you :)

The Pavalue for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05. and (c)g=0 10 P=0.0816 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Fail to reject Ho because the P-value, 0.0816, is less than a = 0.01. O B. Fail to reject H, because the P-value, 0.0816, is greater than a= 0.01. OC. Reject H, because the P-value, 0.0816, is less than a=0.01. O D. Reject Ho because the P-value, 0.0816, is greater thana= 0.01. (b) Do you reject or fail to reject H, at the 0.05 level of significance? O A. Reject Ho because the P-value, 0.0816, is less than a =0.05. O B. Fail to reject H, because the P-value, 0.0816, is greater than a= 0.05. OC. Reject H, because the P-value, 0.0816, is greater than oa 0.05. O D. Fail to reject Ho because the P-value, 0.0816, is less than a = 0,05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? O A. Reject Ho because the…

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a=0.05, and (c) a= 0.10. P=0.0596 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA Fail to reject Hg because the P-value, 0.0596, is greater than a= 0.01. OB. Reject Ho because the P-value, 0.0596, is greater than a= 0.01. OC. Fail to reject Hg because the P-value, 0.0596, is less than a=0.01. %3D OD. Reject Ho because the P-value, 0.0596, is less than a= 0.01. %3D

Which of the following terms describes when the null hypothesis is NOT rejected when it should be rejected? O Significance level, a Type I error Type II error p-Value Alternative hypothesis
