For a onetailed hypothesis test the critical zvalue of the t

For a one-tailed hypothesis test, the critical z-value of the test statistic is -1.17. Which of the following is true about the hypothesis test? = 0.60 for a lower-tailed test = 0.60 for an upper-tailed test = 0.12 for an upper-tailed test = 0.12 for a lower-tailed test

Solution

For a one-tailed hypothesis test, the critical z-value of the test statistic is -1.17.

Thus, = 0.12 for a lower-tailed test is true.
