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,
The null and alternative hypothesis is,
Ho:
$78.52
Ha:
$78.52

For the following statements, state the null and alternative
hypotheses and identify which represents the claim. Determine when
a type I or type II error occurs for a hypothesis test of the
claim. Determine whether the hypothesis test is left-tailed,
right-tailed, or two-tailed, and explain your reasoning. Explain
how you should interpret a decision that rejects the null
hypothesis. Explain how you would interpret a decision that fails
to reject the null hypothesis.

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...
