Hypotheses and summary sample statistics are given for a test for difference in means using paired data. Assume that the conditions are met and the underlying distribution is approximately normal. Test $H_0 : mu_d = 0$ vs $H_a > 0$ when the sample has $ar{x}_d = 1.5$ with $s_d = 7.1$ and $n_d = 20$. Find the value of the t-test statistic and then use the t-distribution to find the p-value. Round your answers to three decimal places. test statistic = p-value = What is the conclusion using a 5% significance level? Reject $H_0$. Do not reject $H_0$.

Step 1: Identify the hypotheses The null hypothesis (Hā) is that the difference in means is equal to 0 (Ud = 0), and the alternative hypothesis (Hā) is that the difference in means is greater than 0 (Ud > 0). Show moreā¦

Hypotheses and summary sample statistics are given for a test for a mean. Assume that the conditions are met and the underlying distribution is approximately normal: Test Ho Ī¼ = 14 vs Ha Ī¼ ā 14 when the sample has xĢ = 7.6 and n = 50. Find the value of the t-test statistic and then use the t-distribution to find the p-value. Round your answers to three decimal places. Test statistic: p-value:

Use the t-distribution and the given matched pair sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distribution of the differences is relatively normal. Assume that differences are computed using d = X1 - X2. Test Ho: Āµ1 = Āµ2 Vs Ha: Āµ1 ā Āµ2 Using the paired data in the following table: Treatment 1 Treatment 2 11 15 9 10 14 17 12 12 15 18 Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places. Test statistic: p-value: Give the conclusion using a 0.05 significance level: Reject Ho or Do not reject Ho.
