a) Response rate= People invited/people participated. 1,727 / 41,000 X 100% = 4.21%
b) Margin of error =1/↓(square root) 1727= 1/41.56 X 100%= 2.41%
c) I do think that the margin of error is a good result is a good measure to determine the accuracy results because the difference between the response rate and margin of error is less than 2%. (guessed)
excercise 4.13
a) An example of a biased question would be going up to people and asking them "would you agree that smoking cigarettes would cause lung cancer?"
b) An example of a question that is confusing to answer would be "do you think the movie Titanic is a good or bad movie, and compare Titanic to the movie called The Dark Knight.
exercise 4.20 (THIS ONE IS PROBABLY WRONG VINCENT)
a) 3 random students= Miller, Convoy, and Fox 2 random faculty members= Dean and Pearl
b) There is a 15% chance that the person named Convoy is chosen (3 / 20 X 100% = 15%). There is a 20% chance that the faculty member Dean is chosen (2 / 20 X 100% = 20 %).
exercise 4.27
200 / 5 = 40. Our line starts from 112. Our 5 rooms would be 32, 72, 112, 152, and 192. (Keep adding 40 and subtracting 40 until you get 5 numbers that are between 0 and 200).
excercise 4.28 NAEIM IS TOO STUPID TO ANSWER THIS
Harris Poll Questions
1. The person who ran the survey was Larry Shannon-Missal (IDK IF THIS IS RIGHT)
2. The target population is people across the United States (IDK IF THIS IS RIGHT)
3. All though the people that were participating in this survey were the people that responded to the Harris Polls, it is difficult to tell what the study population is because they claim that they used "age, sex, race/ethnicity, education, region and household income" were weighted differently to match with the rest of the population from the US. (IDK IF THIS IS RIGHT)
