A 2014 Pew Research Center Survey asked 2,002 adults about the intersection of politics and science. Of the survey participants, 1,281 responded "neither" when asked if they perceive scientists as politically liberal or conservative. What are the values of p′, "successes", or the estimated proportion of Americans who perceive scientists as neither politically liberal or conservative, and q′, the estimated proportion of Americans who perceive scientists as politically liberal or conservative? Answer in decimal form, rounding to the nearest hundredth.
In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 48% with a margin of error of 1.9%. Describe the conclusion about p using an absolute value inequality.
For which reason is it a problem when journalists only report on one study? a. It can lead people to think journalists are scientists. b. It can cause people to interrogate a study’s validities. c. It can lead people to value one study over decades of previous research. d. It can make journalists look bad.
A recent report stated that in 1990, there were approximately 9.7 million employment opportunities in a Science, Technology, Engineering or Mathematics (STEM) related field. There is a reported 17.3 million positions available in a STEM related field in 2019. What is the relative change in the number of STEM positions available from 1990 to 2019? A. 7.6% B. 56.1% C. 43.9% D. 78.4%
In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin or error- the largest (reasonable) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a made up poll, the proportion of people who like dark chocolate more than milk chocolate was 44% with a margin of error of 1.3%. Describe the conclusion about p using an absolute value inequality.
Researchers want to estimate the percentage of people who thought drinking and driving was a serious problem. Reserchers waited outside a bar to question people. They usually find 11%of bar patrons believe drinking and driving is a serious problem. a. identify the populatin of interest b. identify the sample c. identify the population parameter of interest d. identifywho if anyone was left out of the study
A health journal conducted a study to see if packaging a healthy food product like junk food would influence children's desire to consume the product. A fictitious brand of a healthy food product-sliced apples-was packaged to appeal to children. The researchers showed the packaging to a sample of 348 school children and asked each whether he or she was willing to eat the product. Willingness to eat was measured on a 5-point scale, with 1 = "not willing at all" and 5 = "very willing." The data are summarized as x = 3.56 and s=2.19. Suppose the researchers knew that the mean willingness to eat an actual brand of sliced apples (which is not packaged for children) is µ = 3. Complete parts a and b below. a. Conduct a test to determine whether the true mean willingness to eat the brand of sliced apples packaged for children exceeded 3. Use α = 0.10 to make your conclusion. State the null and alternative hypotheses. Ho: H₂:
In a Gallup poll of 1236 adult respondents, 6% said that bad luck follows breaking a mirror. That percentage has a margin of error of 1.5 percentage points. Why is it misleading to state that the percentage is 6% with a margin of error of 1.5%?
Statistics Question
In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 39% with a margin of error of 1.3%. Describe the conclusion about p using an absolute value inequality. The answer field below uses the symbolic entry option in Mobius. That lets you type in a vertical bar | to represent absolute values. Also, when you type in < and then =, the symbolic entry option will automatically convert that to ≤ . In the same way, if you type in > and then =, the symbolic entry option will automatically convert that to ≥. Be sure to use decimal numbers in your answer (such as using 0.40 for 40%).
A pollster wishes to estimate the proportion of United States voters who favor capital punishment. How large a sample is needed in order to be 90% confident that the sample proportion will not differ from the true proportion by more than 5%?
