Question

Need Help Finding Test Statistic (rounded to 3 decimal places), as well as p-value rounded to 4 decimal places. 

You wish to test the following claim (H) at a significance level of a = 0.005.
Ho: P₁ = P2
Ha: P₁ P2
You obtain 44.1% successes in a sample of size n₁ = 544 from the first population. You obtain
34.5% successes in a sample of size n₂ = 328 from the second population. For this test, you
should NOT use the continuity correction, and you should use the normal distribution as an
approximation for the binomial distribution.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic = 3.008 x
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value = 0.0013 x
The p-value is...
less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
Ⓒ reject the null hypothesis
O accept the null hypothesis
O fail to reject the null hypothesis
As such, the final conclusion is that...
O There is sufficient evidence to warrant rejection of the claim that the first population
proportion is greater than the second population proportion.
O There is not sufficient evidence to warrant rejection of the claim that the first population
proportion is greater than the second population proportion.
The sample data support the claim that the first population proportion is greater than the
second population proportion.
O There is not sufficient sample evidence to support the claim that the first population
proportion is greater than the second population proportion.
