3. A manager wants to determine if there is a significant difference between the daily wages for semiskilled workers in two cities. In order to do this, he takes a random sample of daily wages in both cities and finds thatx₁ = Php 300, x₂ = Php 270, $1 = Php 100, S2 Php 90 n1 = 40, n₂ = 54. Test at 5% level of significance.
