Question
From previous studies, it is concluded that 30% of people support the death penalty. A researcher claims that the proportion is significantly different than 30% and decides to survey 400 working adults. Test the researcher's claim at the α=0.01α=0.01 significance level.
Preliminary:
- Is it safe to assume that n≤0.05n≤0.05 of all subjects in the population?
- No
- Yes
- Verify nˆp(1−ˆp)≥10.np^(1-p^)≥10. Round your answer to one decimal place.
nˆp(1−ˆp)=np^(1-p^)=
Test the claim:
- The null and alternative hypotheses are
- H0:p≤0.3H0:p≤0.3
Ha:p>0.3Ha:p>0.3 - H0:μ=0.3H0:μ=0.3
Ha:μ≠0.3Ha:μ≠0.3 - H0:μ≤0.3H0:μ≤0.3
Ha:μ>0.3Ha:μ>0.3
- H0:p=0.3H0:p=0.3
Ha:p≠0.3Ha:p≠0.3 - H0:μ≥0.3H0:μ≥0.3
Ha:μ<0.3Ha:μ<0.3 - H0:p≥0.3H0:p≥0.3
Ha:p<0.3Ha:p<0.3
- H0:p≤0.3H0:p≤0.3
- The test is
- Based on the sample of 400 people, 36% people support the death penalty. What is the test statistic? Round your answer to two decimal places.
- What is the pp-value? Round your answer to four decimal places.
- Make a decision.
- Do not reject the null hypothesis.
- Reject the null hypothesis.
- Make a conclusion.
- There is sufficient evidence that the proportion of people who people support the death penalty is significantly different than 30% at the α=0.01α=0.01 significance level.
- There is not sufficient evidence that the proportion of people who people support the death penalty is significantly different than 30% at the α=0.01α=0.01 significance level.
