Answer #1

The statistical software output for this problem is:

Two sample T hypothesis test: HI : Mean of Sample 1 μ2 : Mean of Sample 2 (with pooled variances) Hypothesis test results: Di

Hence,

Rejection Region:

Option C; -2.8784; 2.8784

Test statistic = 0.2516

is not; do not reject; insufficient
