A survey was conducted to compare the mean cost of a meal at fast food restaurants in two different cities. Sample mean City in $4.05 $0.55 26 32 $0.85 B $5.15 Assume that the population variances of both groups are different. Calculate the test statistic to test whether there is sufficient evidence that the mean costs of a meal at fast food restaurants in two different cities are different.
