Question

Using z the table found in Table E of Appendix C, the critical value for the right-tailed test with  is 1.88.

Quizplus · Accepted Answer

The z-table in Appendix C shows that the critical value for a one-tailed test with a 90% confidence level (which is equivalent to a significance level of 0.1) is 1.28. Since the given test is also a right-tailed test, we need to use the positive value of the critical value, which is 1.28. Therefore, the statement is false and the correct critical value is 1.28, not 1.88. This is true according to the information given in the statement. Table E in Appendix C provides the critical values for one-tailed tests at different levels of significance, and with df=11, the critical value for a right-tailed test with a significance level of 0.05 is indeed 1.88.
