Expediа wоuld like tо test the hypоthesis thаt the аverage roundtrip airfare between Philadelphia and Paris is higher for a flight originating in Philadelphia when compared to a flight originating in Paris. The following data summarizes the sample statistics for roundtrip flights originating in both cities. Assume that the population variances are equal.Originating City PhiladelphiaParisSample mean$1,240$1,060Sample size1519Sample standard deviation$270$240If Population 1 is defined as flights originating in Philadelphia and Population 2 is defined as flights originating in Paris, using α = 0.05, the critical value for this hypothesis test would be ________.
