Consider the following null and alternative hypotheses. H_o:$\mu$= 67 H_a:$\mu$ $\neq$ 67 These hypotheses ______________. A)indicate a one-tailed test with a rejection area in the right tail B)indicate a one-tailed test with a rejection area in the left tail C)indicate a two-tailed test D)are established incorrectly E)are not mutually exclusive

The hypotheses indicate a two-tailed test because the alternative hypothesis specifies that the mean is not equal to 67, which implies that the test is looking for differences in both directions (less than or greater than 67).

Consider the Following Null and Alternative Hypotheses μ\muμ = 67 Ha μ\muμ

Consider the Following Null and Alternative Hypotheses $\mu$ = 67
H_a $\mu$
