At this weekend’s football game, 20 out of the first 50 people who entered the field were not wearing hats. If this sample is representative of the 300 people attending the game, about how many of them will probably NOT be wearing hats? Show all work and justify your answer.

Answers

Answer 1

Answer:

180 People will wear Hats

Step-by-step explanation:

If there are 30 people that wear hats out of 50 we extrapolate that data meaning we just multiply both till we get the disired number of 300, so 50x6 = 300, so 30x6= 180
