Question

Brianna surveyed a representative sample of students at her school to collect data about the numbers of Internet-compatible devices they own. Estimate about how many of the 250 students who attend Brianna’s school own exactly two Internet-compatible devices.

Answer 1

Answer:

125 students

Step-by-step explanation:

The following table is missing:

Number of Devices Number of Students

1                                 18

2                                 25

3 or more                 7

Total                                50  

From the sample, we can estimate that 25/50 = 0.5 or 50% of the students have exactly two Internet-compatible devices. Then there are 0.5*250 = 125 students who have exactly two Internet-compatible devices in Brianna’s school.
