Test the claim about the difference between two population means

μ1
and
μ2
at the level of significance
α.
Assume the samples are random and independent, and the populations are normally distributed.

Claim:
μ1≤μ2;

α=0.05.
Assume
σ21≠σ22

Sample statistics:	x1=2410, s1=177, n1=15 and
	x2=2293, s2=54, n2=9

Find the standardized test statistic t.

Find the P-value.
