    Answer:

    Incorrect

    Step-by-step explanation:

    This interpretation is incorrect because it states that 98% of the data is with in the confidence interval.

    or 98% of the laptop have screen size between 19.2 and 21.4 inches

    However, the interpretation would have been correct if it would have stated as – Value of the population mean i.e mean size of the laptop screen lies within the confidence interval.
