1.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=0.01

Population statistics:

σ1=3.5,

σ2=1.3

Sample statistics:

x1=17,

n1=28,

x2=15,

n2=26

Determine the alternative hypothesis.

Ha:

μ1

not equals≠

μ2

Determine the standardized test statistic.

(Round to two decimal places as needed.)

Determine the P-value.

P-value=nothing

(Round to three decimal places as needed.)

What is the proper decision?

Reject

H0.

There is enough evidence at the

level of significance to reject the claim.

Fail to reject

H0.

There is not enough evidence at the

level of significance to reject the claim.

Reject

H0.

There is not enough evidence at the

level of significance to reject the claim.

Fail to reject

H0.

There is enough evidence at the

level of significance to reject the claim.
