Question

In a random sample survey of 75 people at a high school game, 60 people said that they want the home team to win. If there are a total of 600 people at the football game, how many people would you predict want the home team to win,based on the survey.

Answer 1

480

Explanation:

In order to predict the total number of people, we must make a proportion.

If out of 75 people 60 say yes, then out of 600 people how many would say yes.

Therefore, we have to:

(60/75) * 600 = 480

In other words, 480 people would say yes, keeping the proportion of the random sample that was made before
