6​%
are employed as teachers or teaching assistants. At
α=0.05​,
is there enough evidence to reject the​ researcher's claim? Complete parts​ (a) through​ (e) below.
​(a) Identify the claim and state
H0
and
Ha.
 
Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice.

C.
The percentage of working college students who are employed as teachers or teaching assistants is not
nothing​%.
 
D.
At most
nothing​%
of working college students are employed as teachers or teaching assistants.
Let p be the population proportion of​ successes, where a success is a working college student who is employed as a teacher or teaching assistant. State
H0
and
Ha.
Select the correct choice below and fill in the answer boxes to complete your choice.
​(Round to two decimal places as​ needed.)
 
A.
H0​:
p≠nothing
Ha​:

Ha​:
p≤nothing
​(b) Find the critical​ value(s) and identify the rejection​ region(s).
 
Identify the critical​ value(s) for this test.
 
z0=nothing
​(Round to two decimal places as needed. Use a comma to separate answers as​ needed.)
Identify the rejection​ region(s). Select the correct choice below and fill in the answer​ box(es) to complete your choice.
