A simple random sample ofn1=19measurements from a population with a population standard deviation1=2had a sample mean ofx1=30x. An independent simple random sample ofn2=13measurements from a different population with a population standard deviation2=4had a sample mean ofx2=32x. Test the claim that the population means are different and use a level of significance of=0.04.

a. What is the level of significance?

b. State the null and alternate hypothesis.
