The statistic software output for this problem is:

Two sample T summary hypothesis test: Hi : Mean of Population 1 H2 : Mean of Population 2 H1 - H2 : Difference between two means Ho : H1 - H2 = 0 HA: Ni - 2 0 0 (without pooled variances) Hypothesis test results: Difference Sample Diff. Std. Err. DF T-Stat M1 - 2 -0.33 0.20052184 39.124649 -1.645706 P-value 0.1078

Test statistics = -1.65

P-value = 0.108

Option A)
