Answer:
125 students

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.
