Question

**ch6 ex210**: 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 : μ1=μ2 vs Ha : μ1≠μ2

using the sample results x¯1=15.3, s1=11.6 with n1=100 and x¯2=18.4, s2=14.3 with n2=80
