Based on the data, what is the most reasonable estimate for the number of Trinity Food Festival attendees whose favorite type of pizza is sausage pizza?
Choose 1
They surveyed 40 people in total and out of those 40, 21 said that sausage pizza was their favorite pizza.
The percentage of people who prefer sausage pizza is therefore:
= 21/40 * 100%
= 52.5 %
If there are 1,600 people in the festival and we assume that the sample is a representation of the people there, the estimated number of people who prefer sausage pizza will be:
For this case the first thing we should do is find the percentage of people surveyed who said that pizza pizza was their favorite type of pizza. We have then: We are now looking for 52.5% of 1600 people. For this, we make the following rule of three: 1600 ----------> 100% x ---------------> 52.5% Clearing the value of x we have:
the most reasonable estimate for the number of Trinity Food Festival attendees whose favorite type of pizza is sausage pizza is: x = 840
