- Which locations had the highest and lowest abundance of fungal spores? Why do you think you got these results? *Outside Cass refers to outdoors*A researcher reports t (12) = 2.86, p <.05 for a repeated measures research study. How many individuals participated in the study?In order to cut the margin error in half, what must we do? Group of answer choices Multiply the sample size by 4. Divide the sample size by 4. Divide the sample size by 2. Multiply the sample size by 2.
- The given population is 3476, n = 528, what will be the value of e (margin of error)? Show clear solutionsBased on a recent survey of adults in 60,000 households, a labor department reported an unemployment rate of 4.8%. The margin of error was 0.1 percentage point.When 410 college students were surveyed,150 said they own their car. Find a point estimate for p (p-hat), the population proportion of students who own their cars.
- P(35<x<39) 50 murders surveyed 0.61% of the murders were clearedBefore the 2008 presidential campaign, the Gallup Poll asked a sample of 1,000 people for whom they would vote for president; 52% said Obama. The margin of error announced by news reports of this poll was A. ± 2%. B. ± 3%. C. ± 8%. D. ± 4%. E. ± 6%Total respondents/population: 54 Using Slovin's Formula, What is the sample respondent if your research paper is 99% accurate? Note: First find the margin of error before solving.
