Test the claim about the difference between two population means 1 and 2

at the level of significance .

Assume the samples are random and independent, and the populations are normally distributed.Claim: 1=2; =0.10.

Sample statistics:	x1=31.9, s1=3.3, n1=12 and
	x2=33.4, s2=2.4, n2=18

Identify the null and alternative hypothesis.

Find the standardized test statistic t.

Find the P-value

Decide whether to reject or fail to reject the null hypothesis.
