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 H0 : ? = 80 vs Ha : ? ? 80 when the sample has x? = 85 with s = 24.3 and n = 12. 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 =

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 H0: μ = 10 vs Ha: μ ≠ 10 when the sample has x̄ = 11.8 with s = 8.1 and n = 30. 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 H0. Do not reject H0.

Use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5% significance level. Assume the results come from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal. Test H0 : μ = 15 vs Ha : μ > 15 using the sample results x̄ = 17.2, s = 6.4, with n = 40. (a) 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. (b) What is the conclusion? Reject H0. Do not reject H0.

Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p = 0.5 vs Ha : p > 0.5 using the sample results p̂ = 0.60 with n = 75 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 = Conclusion: H0.
