1st question: Find the standardized test statistic, t, to test the claim that u1=u2. Two samples are randomly selected and come from populations that are normal. The sample statistics are given below. Assume that o 2 (over)1 not equal to o 2 over 2.

N1= 25, N2= 30, X1=27, X2= 25, S1= 1.5, S2= 1.9

2nd question: Find the standardized test statistic, z to test the claim that p1=p2. The sample statistics listed below are from independent samples.

n1=50, x1=35, n2=60, x2= 40

If anyone can help me I would really appreciate it
