Question 1158094: For a one-tailed hypothesis test, the critical z-value of the test statistic is -2.33. Which of the following is true about the hypothesis test?A. alpha = 0.05 for a lower-tailed test
B. alpha = 0.01 for a lower-tailed test
C. alpha = 0.05 for an upper-tailed test
D. alpha = 0.01 for an upper-tailed test

-2.33 would be significant for a lower tail test where Ha: mean 1 < mean 2
-2.33 is at the 1st percentile of the normal curve, and for a 1-tail test, that would be alpha of 0.01
B.
