Answer 1

Solution: The test is a two-tailed test. Critical values are: -1.645, 1.645 Hence, the rejection region = (-0, -1.645) U (1.645,00) Part-A: Given, z = 1.605 The above value of z = 1.605 does not fall in the rejection region. Hence, we fail to reject Ho because – 1.645 < z < 1.645 Option-A is the correct answer. Part-B: Given, z = 1.693 The above value of z = 1.693 falls in the rejection region. Hence, we reject Ho because z > 1.645 Option-D is the correct answer. Part-C: Given, z= -1.499 The above value of z = -1.499 does not fall in the rejection region. Hence, we fail to reject Ho because – 1.645<z < 1.645 Option-A is the correct answer. Part-D: Given, z= -1.848 The above value of z = -1.848 falls in the rejection region. Hence, we reject Ho because z < -1.645 Option-D is the correct answer.
