Hours Studying per Night vs. Grade-Point Average Hours studying per night, x Grade-point average, y 0.4 2.0 0.9 2.4 1.5 2.6 2.2 3.1 2.6 3.5 3.3 3.8 If the data are entered into a regression calculator, what is the approximate y-intercept of the resulting regression line? A calculator screen. A 2-column table with 6 rows titled Data. Column 1 is labeled x with entries 0.4, 0.9, 1.5, 2.2, 2.6, 3.3. Column 2 is labeled y with entries 2, 2.4, 2.6, 3.1, 3.5, 3.8. The linear regression equation is y almost-equals 0.628 x + 1.759; r almost-equals 0.994. –1.76 –0.63 0.63 1.76
