    19

    Step-by-step explanation:

    Here df denote the degree of freedom

    The degree of freedom are the value which are free to vary

    The degree of freedom can be calculated by subtracting one from the total sample space

    Here total sample space that is n is given as 19

    So degree of freedom that df = 20-1 = 19

    So for the given question the degree of freedom will be 19
