3. 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=0.10.

Assume

σ21≠σ22

Sample statistics:	x1=2407, s1=179, n1=15 and
	x2=2306, s2=50, n2=11

a.Identify the null and alternative hypotheses.

b. Find the standardized test statistic t.

(Round to two decimal places as needed.)

c. Find the P-value.
