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: 1x = 648, 21s = 120, and 1n = 100
x = 495, 22 District Y: 2
s = 140, and 2
n = 90
Verify at 0.05 level of significance whether the sample results support the claim of the organization.
