In a test of hypothesis, the null hypothesis is that the population mean is equal to 50 and the alternative hypothesis is that the population mean is greater than 50. The test is to be made at the 1% significance level. The critical value of z is:

Step 1
- The null hypothesis (H0) states that the population mean, μ, is equal to 50: H0: μ = 50. - The alternative hypothesis (H1) states that the population mean is greater than 50: H1: μ > 50. - This is a one-tailed test because the alternative hypothesis is looking Show more…

Suppose you are testing the null hypothesis that a population mean is less than or equal to 80, against the alternative hypothesis that the population mean is greater than 80. If the sample size is 49 and alpha = .10, the critical value of z is __.

A hypothesis will be used to test that a population mean equals 5 against the alternative that the population mean is less than 5 with known variance $\sigma$. What is the critical value for the test statistic $Z_{0}$ for the following significance levels? (a) 0.01 (b) 0.05 (c) 0.10

We have given the value obtained for the test statistic, $z,$ in a one-mean z-test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine the P-value in each case and decide whether, at the $5 \%$ significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. Right-tailed test: a. $z=2.03$ b. $z=-0.31$
