Pairs of hypotheses about a claim (a statistic of the population, like its mean, μ) include the following: (A) H0: μ ³ k and Ha: μ < k, where k is some value (B) H0: μ = k and Ha: μ ≠ k, where k is some value (C) H0: μ > k and Ha: μ £ k, where k is some value (D) H0: μ £ k and Ha: μ > k, where k is some value (E) H0: μ < k and Ha: μ ³ k, where k is some value
Is the average time to complete an obstacle course longer when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye. Time to Complete the Course Right 46 48 42 50 46 43 50 41 Left 45 46 42 50 46 39 50 37 Assume a Normal distribution. What can be concluded at the the a = 0.05 level of significance level of significance?
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p=0.6 versus H₁: p > 0.6 n = 200; x = 125; a = 0.05 Click here to view page 1 of the table. Click here to view page 2 of the table. Calculate the test statistic, Zo- Zo = (Round to two decimal places as needed.) Identify the P-value. P-value= (Round to three decimal places as needed.) Choose the correct result of the hypothesis test for the P-value approach below. OA: Reject the null hypothesis, because the P-value is greater than α. OB. Reject the null hypothesis, because the P-value is less than α. OC. Do not reject the null hypothesis, because the P-value is greater than α. O D.

Claim: μ=40; α=0.04; σ=3.88. Sample statistics: x=38.2, n=72 the null and alternative hypotheses: H0: μ=40 Ha: μ≠40 calculate the standardized test statistic. The standardized test statistic is enter your response here. (Round to two decimal places as needed.)
Identify the relevant the decision for the test, H0: μ = 2,500 vs. Ha: μ > 2,500 at α = 0.01 for an observed significance p = 0.018. Group of answer choices Since p ≤ α, the decision is not to reject H0. Since p > α, the decision is not to reject H0. Since p > α, the decision is to reject H0. Since p ≤ α, the decision is to reject H0. Since p > α/2, the decision is to reject H0.
