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
