Consider the hypothesis test $ H_{0}: \mu_{1}=\mu_{2} $ against $ H_{1}: \mu_{1} \neq \mu_{2} $ with known standard deviations $ \sigma_{1}=10 $ and $ \sigma_{2}=5 $. Suppose that sample sizes $ n_{1}=10 $ and $ n_{2}=16 $ and that $ \bar{x}_{1}=4.8 $ and $ \bar{x}_{2}=7.9 $. Use $ \alpha=0.05 $. (a) Test the hypothesis and find the $ P $-value. (b) What is the power of the test in part (a) for a true difference in means of 3 ? (c) Assuming equal sample sizes, what sample size should be used to obtain $ \beta=0.05 $ if the true difference in means is 3 ? Assume that $ \alpha=0.05 $. (a) The null hypothesis $ \checkmark $ rejected. The $ P $-value is . Round your answer to three decimal places (e.g. 98.765). (b) The power is i . Round your answer to two decimal places (e.g. 98.76). (c) $ n_{1}=n_{2}= $ i . Round your answer up to the nearest integer.
