Question

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 Upper H Subscript 0 Baseline : mu Subscript 1 Baseline equals mu Subscript 2 vs Upper H Subscript a Baseline : mu Subscript 1 Baseline not-equals mu Subscript 2 using the sample results x Overscript bar EndScripts Subscript 1 Baseline equals 15.3, s Subscript 1 Baseline equals 11.6 with n Subscript 1 Baseline equals 100 and x Overscript bar EndScripts Subscript 2 Baseline equals 18.4, s Subscript 2 Baseline equals 14.3 with n Subscript 2 Baseline equals 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 equals p-valueequals

What is the conclusion of the test? Test at a 10% level.
