    The true statements are: A, C and D

    Step-by-step explanation:

    According to the data of the table:

    18 Students own 1 Internet-compatible devices. 25 Students own 2 Internet-compatible devices. 7 Students own 3 or more Internet-compatible devices.

    So, we will check the options according to the given dа ta:

    A. Students are more likely to own exactly 2 devices than any other number.

    True ⇒ Because the number of students own exactly 2 devices is greater than the other categories.

    B. More students own 3 devices than own more than 3 devices.

    Wrong ⇒ Because there is no information, all we know there are 7 students own 3 or more devices.

    C. Less than half as many students own 3 or more devices as compared to students who own 1 device.

    True ⇒ 18 students own 1 device, the half of them is 9, and the number of students own 3 or more devices is 7 which is less than 9.

    D. About 10 more students own 1 device than own 3 or more devices.

    True ⇒ The difference between students own 1 device and those own 3 or more devices = 18 - 7 = 11 which is about 10 more.

    E. None of the students own exactly 5 devices.

    Wrong ⇒ Because there is no information about this.

    The true statements are: A, C and D
