In a a test of hypothesis the probability of maxing a Type I

In a a test of hypothesis the probability of maxing a Type II error is 0.25. The power of this test is: a. 0.25 b. 0.75 c. 1 d. 0 e. none of the above With all else held constant, performing multiple comparisons without choosing an adjustment method results in: a. Inflated Type I error b. Inflated Type II error c. Both of the above d. Greater power In a certain test of hypothesis the critical t value is 2.07. Under this condition the null hypothesis would be rejected for all except the following observed t values (i.e. find the observed t value at which null hypothesis cannot be rejected): a. 1.01 b. 10.01 c. 100.01 d. 1000.01 e. none of the above All of the following are steps in a test of hypothesis except: a. specify the level of significance b. form the null and alternative hypotheses c. calculate observed value of the test statistic d. all of the above are steps in a test of hypothesis e. none of the above are steps in a test of hypothesis When a judge sends an innocent person to jail he is making a: a. Type I error b. Type II error c. Type III error d. Type IV error e. none of the above

Solution

#

b. 0.75

#

a. Inflated Type-I error.

#

a.1.01 (Since the it is not mentioned whether the test is right tailed or left tailed it is not possible to answer)

#

d.all of the above are steps in a test of hypothesis.

#

a. Type_I error .
