Question Details

In a two-tailed hypothesis test the test statistic is determined 




	1.	For a one-tailed test (upper tail) at 93.7% confidence, Z =
a.	1.50
b.	1.96
c.	1.645
d.	1.53


		

	2.	For a one-tailed test (upper tail), a sample size of 26 at 90% confidence, t =
a.	1.316
b.	-1.316
c.	-1.740
d.	1.740


	

	3.	For a one-tailed test (lower tail) with 22 degrees of freedom at 95% confidence, the value of t =
a.	-1.383
b.	1.383
c.	-1.717
d.	-1.721


	

	4.	For a one-tailed hypothesis test (upper tail) the p-value is computed to be 0.034. If the test is being conducted at 95% confidence, the null hypothesis
a.	could be rejected or not rejected depending on the sample size
b.	could be rejected or not rejected depending on the value of the mean of the sample
c.	is not rejected
d.	is rejected


	

	5.	In a two-tailed hypothesis test the test statistic is determined to be Z = -2.5. The p-value for this test is
a.	-1.25
b.	0.4938
c.	0.0062
d.	0.0124
