A store owner wanted to determine the number of new customers at her store. She surveyed a random sample of 25 customers. The results are shown in the list, where
each 1 represents a new customer and each 2 represents a returning customer.
21212
12221
22222
22222
21122
Based on this sample, how many of the next 250 customers will be new customers?

60

Step-by-step explanation:

To solve this problem, you first have to figure out how many customers put 2 and how many customers put 1. To do this, you count the amount of 2's on the survey, which is 19. Then, you count the amount of 1's, which is 6.

Then, you divide both of them by 25, since that is the number of customers that were surveyed. 6 divided by 25 is 24% and 19 divide by 25 is 76%. Therefore, 24% of the customers were new.

So, you do 250 times 24% (or 0.24 in decimal form) and you will get 60.

So, there will be an estimated amount of 60 customers out of the next 250 that are new.
