A research organization claims that the monthly wages of industrial workers in district X

exceeds that of those in district Y by more than Rs 150. Two different samples drawn
independently from the two district yielded the following results:
District X: 1 x = 648, 2
1 s
= 120, and 1 n = 100
District Y: 2 x = 495, 2
2 s = 140, and 2 n = 90
Verify at 0.05 level of significance whether the sample results support the claim of the
organization.
