Answer 1

First problem : Europe versus Asia

Result :

t-Test: Two-Sample Assuming Unequal Variances Europe Asia Mean 878.571429 841.625 Variance 143017.952 260726.2679 Observations 7 8 Hypothesized Mean Difference 0 df 13 t Stat 0.16045185 P(T<=t) two-tail 0.87499159 t Critical two-tail 2.16036865

Test statistic value and critical value :-

0.16045185 test Statistic t Critical two-tail 2.16036865
