Jun 22, 2020 · We assess such a hypothesis by taking the null hypothesis as the default, and if its p-value is too low we may find the alternative hypothesis more convincing. Or we may not: if our null hypothesis says half the marbles are red and the alternative hypothesis says most are red, data in which few if any marbles are read makes both hypotheses look ...

Question: 16-A test is conducted with the null hypothesis H 0: μ = 10 vs. the alternative hypothesis H a: μ < 10 at the α = 0.05 level. The test statistic is z = –1.75. The correct conclusion is: fail to reject the null hypothesis reject the null hypothesis only possible at the α = 0.01 level 17-The null and alternative hypotheses are ...

Mar 19, 2018 · The correct hypotheses are: $$\begin{align} H_0: \ \mu=540 \\ H_1: \ \mu <540 \end{align}.$$ Interpretation: The problem states "mean=540 seconds", so is the null hypothesis. To improve mean call time implies to decrease the mean call time by more efficient work of the call center operators.
