Question: Having just been charged more to fly from Toronto to Saint John than from Toronto to Britain, an annoyed passenger claims there is no difference

Having just been charged more to fly from Toronto to Saint John than from Toronto to Britain, an annoyed passenger claims there is no difference in price between domestic and international flights. Using ads in the Toronto Star, his travelling companion compiles a random sample of prices for domestic flights from Toronto and flights from Toronto to Europe. Based on his results, shown below, test the disgruntled passenger's claim that there is no difference in price between these two types of flight. Use the 0.02 level of significance. Assume unequal standard deviations for the two samples.
