A hypothesis test is performed at the 10% significance level to determine if the mean time of faculty contact (in hours per week) with students at research universities and non-research universities are different. The hypotheses were determined and data was collected in the table below for both samples.



  • H0:μ1≥μ2, Ha:μ1<>

  • α=0.1



ResearchNon-ResearchSample Size2016Sample Mean9.716.8Sample St. Dev.1.73.2

What is the test statistic (t-value) for this two-mean hypothesis test?








Select the correct answer below:










t=20−16(9.7)21.7+(16.8)23.2√≈0.33







t=1.7−3.2(9.7)220+(16.8)216√≈−0.32







t=9.7−16.8(20)21.7+(16)23.2√≈−0.4







t=1.7−3.2(20)29.7+(16)216.8√≈−0.2







t=9.7−16.8(1.7)220+(3.2)216√≈−8.02







t=20−16(1.7)29.7+(3.2)216.8√≈4.2
