A 95% confidence interval for $\mu$ is computed to be (2.05, 3.60). For each of the following hypotheses, state whether $H_0$ will be rejected at 0.05 level. Part: 0/4 Part 1 of 4 $H_0: \mu = 2$ versus $H_1: \mu \neq 2$ Since the 95% confidence interval does not contain $\mu_0$, then $H_0$ will be rejected at the 0.05 level. Part: 1/4 Part 2 of 4 $H_0: \mu = 1$ versus $H_1: \mu \neq 1$ Since the 95% confidence interval does not contain $\mu_0$, then $H_0$ will be rejected at the 0.05 level.
