A data set whose original x values ranged from 120 through 351 was used to generate a regression equation of ŷ=0.06x + 14.2. Use the regression equation to predict the value of y when x=352.

    35.32

    Step-by-step explanation:

    The regression equation usually demonstrated as

    y=a+bx.

    In the above equation y is the dependent variable, x is the independent variable, a is the intercept of regression line and b is the slope of regression line.

    The given regression equation is

    y^=0.06x+14.2

    The predicted value of y can be computed by simply putting the value of x in above equation.

    So,

    y^=0.06 (352) + 14.2

    y^=21.12+14.2

    y^=35.32

    Thus, the predicted value of y for x=352 is 35.32.
