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



test statistics=(x1 bar- x2 bar)(s1^2/n1)(s2^2/n2)
substitute the values and you will get the answer.
I got this answer. please check it.
(x1 bar- x2 bar)(s1^2/n1)(s2^2/n2)
Therefore,Statistics = 285.6
