    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.
