MATH 312 Lecture Notes - Lecture 9: Wii
Document Summary
They decide they want to sell raffle tickets for a wii, but they want to know how many people would be interested in buying raffle tickets. In this school there are grades 1-6 with 100 kids in each grade. Doug wants the same number of boys and girls from each grade so he randomly selected 5 boys and 5 girls from each grade, 30% said they would be interested. It does not guarantee that every class has 50 girls and 50 boys. Thus, the probability of a girl being selected could be higher compared to that of a boy. Options for polling 10 kids from one grade: number each student {1, 2 100} and randomly select 10 random numbers from a hat. If using a table of random numbers, we can assign each student a number. One option would be if we pulled a random sample of sufficient size and recorded the properties of red and green balls.
