Transcribed Image Text:You wish to test the following claim (Ha) at a significance level of a = 0.20.
Ho: P₁ P2
H₁: Pi>P2
You obtain 174 successes in a sample of size n₁ = 483 from the first population. You obtain 157 successes
in a sample of size n2 = 506 from the second population.
What is the test statistic for this sample? (Report answer accurate to two decimal places.)
test statistic =
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value=
The p-value is...
O less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
O reject the null
O accept the null
O fail to reject the null
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.
O 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.
