You generate a scatter plot using Excel. You then have Excel plot the trend line and report the equation and the \( r^2 \) value. The regression equation is reported as \[ \hat{y} = 29.24x + 12.12 \]and the \( r^2 = 0.1444 \).What is the correlation coefficient for this data set? (Round to two decimals if needed.)[Text box for input][Submit Question button]

In the regression analysis, the coefficient of determination is used to measure the explained sum of squares as a proportion of the total sum of squares. Coefficient of determination (R2) is a squared value of the correlation coefficient. For this case, the correlation coefficient can be calculated as: r=r2=0.1444=0.38 Since, the value of b1 is given as +29.24, which is positive. Hence, it can be concluded that the dependent variable and independent variable are positively related. Hence, the correlation coefficient is 0.38. Hence, r=0.38
