solution
(A)
this is the right tailed test .
The null and alternative hypothesis is ,
H0 : 
= 38725
Ha :
> 38725
(B)this is the left tailed test .
The null and alternative hypothesis is ,
H0 :
= 68.32
Ha :
< 68.32
(C)
this is the two tailed test .
The null and alternative hypothesis is ,
H0 :
= 22.95
Ha :
22.95

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.
