An education researcher claims that 57% of college students work year-round. In a random sample of 400 college students, 228 say they work year-round. At a=0.10, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below. Let p be the population proportion of successes, where a success is a college student who works year-round. State Ho and H₂. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) OA. Ho: P H₂: p OD. Ho: P< Ha: p2 OB. Ho ps H₂:p> OE. Ho: P (b) Find the critical value(s) and identify the rejection region(s). Identify the critical value(s) for this test. RICE H₂:p= ☐☐ ☐ OC. Ho: p² Hap< OF. Ho:p> Ha: ps

Show supporting work for each section 

identify the claim & state H0 & Ha fill in blanks 

identify critical value(s) z0=
and rejection region with graph & greater than or lesser than symbols 

find the standardized test statistic z=

Decide whether to reject or fail to reject the null hypothesis 

interpret the context of the Original Claim 

5) Complete all parts:
a. State the null and alternative hypotheses. Make sure you are stating your
hypotheses in terms of the correct variable (u or p). If there is a claim, identify
which hypothesis is the claim by writing CLAIM to the left of it.

b. Sketch and properly shade the rejection region and label with the correct critical
value. Make sure to clearly label whether your critical value is a za or ta.
c. Calculate the test statistic accurate to three decimal places; show your work
(including the formula you used) and enter your value in the space below
