Test the null hypothesis H0: Ļ = 0 versus H1: Ļ ā 0 given a sample correlation of 0.18 for a random sample of size n = 40. Use a 10% significance level. Find the t-statistic. t = (Round to three decimal places as needed.) p-value = reject or not reject
Added by Andrew K.
Step 1
18 \) and \( n = 40 \), we can plug in the values: \[ t = \frac{0.18}{\sqrt{\frac{1-0.18^2}{40-2}}} \] \[ t = \frac{0.18}{\sqrt{\frac{1-0.0324}{38}}} \] \[ t = \frac{0.18}{\sqrt{\frac{0.9676}{38}}} \] \[ t = \frac{0.18}{\sqrt{0.02547}} \] \[ t = Show moreā¦

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: Ī¼ = 500 vs Ha: Ī¼ ā 500 using the sample results xĢ = 432, s = 118, with n = 75. (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. Test statistic = _________________ p-value = ___________________ (b) What is the conclusion? ___Reject H0. ___Do not reject H0.

Use the t-distribution and the given 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 distributions are relatively normal. Test H0: Ī¼1 = Ī¼2 vs Ha: Ī¼1 ā Ī¼2 using the sample results xĢ1 = 15.3, s1 = 11.6 with n1 = 100 and xĢ2 = 18.4, s2 = 14.3 with n2 = 80. (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. Test statistic = p-value = (b) What is the conclusion of the test? Test at a 10% level. Reject H0. or Do not reject H0.
