Document Summary
Chapter 19 notes: the newscaster means that true proportion of the results of the poll are plus or minus 4% from his/her estimation. Sample = 134 of the cars stopped p = cars that are stopped with safety problems p(hat) = cars that were not stopped that might have car safety issues. Considering that the sample of drivers were independent from each other (one car wouldn"t in- Uence another car in terms of car safety). Furthermore, so long as the sample is within the sample size assumption, we can use the methods in this chapter. Sample = 602 of the people who visited the website p = people from the general public who are in favor of prayer. p(hat) = people from the general public who are not in favor in prayer. Considering this sample is not purely random, we would be unable to use the methods from this chapter. Population = all parents of students who attend this school.
