    Answer

    A certain scale is not calibrated correctly,

    Mass displayed as 0.75 kilogram less than its actual mass.

    The scale of display will be equal to '1'

    The correlation between actual mass and displayed mass is 1 because correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.

    So, the correct answer will be "1"
