    d) If the correlation coefficient is less than zero, the slope of the regression line will be negative.

    Step-by-step explanation:

    We have to find the statement free of errors.

    a) The variables have a correlation of 1.96

    The above statement is wrong as coefficient of correlation ranges from 0 to 1.

    b) The correlation between students' genders and their height is 0.92.

    The given statement is wrong as gender is a categorical variable.

    c) There is almost no correlation between the variables, since r - 0.998.

    The given statement is wrong as there is a strong negative correlation between the two variable.

    d) If the correlation coefficient is less than zero, the slope of the regression line will be negative.

    The following statement is correct
