A test is conducted with alternative hypothesis Ha: μ > 85, and the p-value is p = 0.007. Would you reject or fail to reject H0 at the 0.01 level of significance? Group of answer choices reject H0 not sufficient information to decide fail to reject H0
If a hypothesis test were performed at the .01 level of significance, for which of the following p-values should we reject H0? Group of answer choices .235 .060 .058 .015 .002
We wish to test the claim that μ > 32 at a level of significance of α = 0.05. The sample statistics are n = 50, and x-bar = 32.3. Moreover, it is known that the population mean is s = 12. Compute the test statistic, rounded to two decimal places. Group of answer choices 3.11 0.98 2.31 1.77
Decide whether or not to reject the null hypothesis in favor of the alternative hypothesis at significance level α=0.05 α=0.05 based on the following information: n=32, HA: μ>200: μ>200, T=2.1. I recommend that you sketch the area that represents the p-value.

Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.
Test the claim about the population mean μ at the level of significance α. Assume the population is normally distributed. Claim: μ = 1400; α = 0.01; σ = 82 Sample statistics: = 1370, n = 35
Test the claim about the population mean μ at the level of significance α. Assume the population is normally distributed. Claim: μ ≠ 33; α = 0.05; σ = 2.7 Sample statistics: = 32.1, n = 35
In order to test the following hypotheses at an α level of significance H0: μ ≤ 800 Ha: μ > 800 the null hypothesis will be rejected if a) the test statistic z ≥ zα. b) the test statistic z < zα. c) the test statistic z < −zα. d) the test statistic z = α.
Decide whether or not to reject the null hypothesis in favor of the alternative hypothesis at significance level α = 0.05 α=0.05 based on the following information: n = 32 n=32, HA : μ ≠ 200 H A :μ =200, T = 0.001 T=0.001. I recommend that you sketch the area that represents the p-value.
