The value of the test statistic for a two-tailed one-mean z-test is z 1.52. Determine the p-value. (Round to four decimal places.) Answer: 0.1285
You are conducting a two-tailed hypothesis test to see if your sample mean (x̄) differs significantly from your population mean (μ = 50). Your alpha level is 0.05 (α = 0.05). Sample data: 53, 56, 59, 64, 55, 42, 36, 58, 39, 53, 62, 60, 64, 53, 42, 53, 65, 60, 61, 63 You will need to: h) State your alternative hypothesis and null hypothesis i) Calculate the sample mean (x̄) j) Calculate the sample standard deviation (s) k) Calculate...
For a one-tailed hypothesis test, the computed test statistic is z= 2.65. What is the p-value?
What is the p-value of a right-tailed one-mean hypothesis test, with a test statistic of z0=0.57? (Do not round your answer; compute your answer using a value from the table below.)

The value obtained for the test statistic, z, in a one-mean 2-test is given. Whether the test is two tailed, left tailed, or right tailed is also specified. For parts (a) and (b). determine the P-value and decide whether, at the 1% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. a. The test statistic in a two-tailed test is z= -1.42. The P-value is (Round to three cocimal places as...
