Solution:

A.

Claim : The average income of nurses is at most $36,650.

This a right (One) tailed test.

The null and alternative hypothesis is,  

Ho: 36650

Ha: 36650

B.

Claim : The average price of a cd is $25.59.

This is a two tailed test.

The null and alternative hypothesis is,

Ho: $25.59.

Ha: $25.59.

C.

Claim : The average electric bill for residents of White Pine Estates is smaller than $78.52 per month.

This is a left (One) tailed test,

For the question below, state what your null and alternative hypotheses are and select the appropriate test. Assess assumptions and do whatever needs to be done depending on your results (ie, doing a transformation of data or selecting a non-parametric if data violate assumptions). If you decide to run a Kruskal-Wallis test, you can assume the data satisfy those assumptions. Recall that it is generally considered ok to violate one assumption, especially if sample size is not too small. Perform...
