Question
From previous studies, it is concluded that 50% of workers were employed from networking. A researcher claims that the proportion is smaller than 50% and decides to survey 500 working adults. Test the researcher's claim at the a=0.05 significance level.
- Is it safe to assume that n≤0.05 of all subjects in the population?
- No
- Yes
- Verify np(1-p)≥10. Round your answer to one decimal place.
np(1-p)= - The null and alternative hypotheses are
- Ho: μ =0.5
Ha:μ ≠0.5 - Ho:p≤0.5
Ha:p>0.5 - Ho:p=0.5
Ha:p≠0.5
- Ho:μ ≤0.5
Ha:μ >0.5 - Ho:μ ≥0.5
Ha:μ <0.5 - Ho: p≥0.5
Ha :p<0.5
- Ho: μ =0.5
- The test is
a.right-tailed or b. two-tailed or c. left-tailed - Based on the sample of 500 people, 45% workers were employed from networking. What is the test statistic? Round your answer to two decimal places.
- What is the p-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 not sufficient evidence that the proportion of people who workers were employed from networking is smaller than 50% at the a=0.05 significance level.
- There is sufficient evidence that the proportion of people who workers were employed from networking is smaller than 50% at the a=0.05 significance level.
