Left-tailed test, z = -1.20, a = 0.10 z=-1.20 = 0.115 = P The p-value for the left-tailed hypothesis test with a test statistic of z = -1.20 is P = 0.115. Because 0.115 > 0.1, you should fail to reject H sub 0. page 357 No.4 right-tailed test z= 1.23

Unformatted text preview: a=.10 P value for right-tailed test has a z= 1.23 and P= .8907. Since 1.23> .8907 you should not fail to reject H sub 0. Because 1.23 on standard deviation chart = .8907 which would be P. If it is less than the z test you fail to reject the Ho....
