    Answer:

    Percentage of error by Clare is estimated as 4.1667 %

    Step-by-step explanation:

    Height measured by Clare = 4 feet

    Height measured by Doctor = 4 feet, 2 inches

    Percentage error = ?

    Percentage error = Difference/ Actual height *100

    Percentage error = (2/ (4*12))*100

    Percentage error = 4.1667 %

    The accurate height is measured by Doctor, as he have more accurate measurement system.
