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. Assume the population to be approximately with equal variances. Step 1. Null & Alternative hypotheses(. Step 2. Level of Significance: 0.05 Step 3: Find the critical value ( df= n₁ + n₂ - 2 Step 4. s2p= (n₁-1)(s₁)² (n2-1)(S2)² n₁+n2-2 Tabular value:1.960 Normal Curve:
