    The box plots below show the lifespan, in months, of laptop batteries manufactured by four companies: box plot labeled Company A shows minimum at 19, first quartile at 19.5, median at 23, third quartile at 23.5, and maximum at 24. Company B shows minimum at 21, first quartile at 22, median at 24, third quartile at 25, and maximum at 26. Company C shows minimum at 20, first quartile at 21, median at 22, third quartile at 24, and maximum at 28. Company D shows minimum at 19, first quartile at 20, median at 22.5, third quartile at 23.5, and maximum at 27. Based on the data, which company's batteries have the highest median lifespan? Company A Company B Company C Company D

    Notice that the line separating the quartiles is the "median" and no other.

    Note that in most cases mean is slightly below the 50th percentile because mean represents the overall aggregate of all samples

    on the other hand, median represents exactly the 50th percentile

    Therefore according to your question the Company B manufactures laptops with batteries that last longer than those manufactured by any other companies.
