a) State the procedure for testing difference between two population mean with equal variances and two population having sample sizes less than 30.

Test the claim the 1st population mean is greater than 2nd population mean by 2 units. Use 5% level of significance

B) Find Mean and variance of sampling distribution of variable Y as;
y=〖(x〗_1+x_2+x_3+⋯x_n)/n Where x_1,x_2,…,x_n are normally distributed.
