Question 548417
I can't seem to get this at all and would appreciate some help 
A political strategist believes that at least 58% of voters in a certain state support his candidate. He then commissions a poll of 1000 voters and 60% of them support his candidate. At α = .05, test the claim.
----
Ho: p <= 0.58
Ha: p > 0.58 (claim)
------------------------------- 
a) State the hypotheses and identify the claim
b) Find the critical values
CV = 1.645
-------------------
c) Compute the test values
z(0.6) = (0.6-0.58)/sqrt[0.58*0.42/1000] = 1.2814
------
d) Make the decision
Since the test value is not in the reject interval,
fail to reject Ho.
----------------------
e) Summarize the results
The test results do not support the claim.
