What's inside
- For hours spent studying (x, hours) and exam mark (y, %): (1, 46), (2, 55), (3, 61), (4, 68), (5, 74), (6, 84). Find the equation of the least-squares line in the form y = a + bx (a and b to 2 decimal places).
- Using the least-squares line y = 39.27 + 7.26x, predict y when x = 5, and state whether this is interpolation or extrapolation (the data ranges from x = 1 to x = 6). Give the prediction to 1 decimal place.
- Using the same line y = 39.27 + 7.26x, predict y when x = 10, and state whether this is interpolation or extrapolation. Give the prediction to 1 decimal place, and note the reliability of this prediction.
- Interpret the slope of the least-squares line y = 39.27 + 7.26x in the context of exam mark and hours spent studying.
- For hours of TV watched per day (x, hours) and test score (y, %): (0, 88), (1, 80), (2, 77), (3, 63), (4, 56), (5, 53). Find the equation of the least-squares line in the form y = a + bx (a and b to 2 decimal places).
- Using the least-squares line y = 88.14 - 7.46x, predict y when x = 1, and state whether this is interpolation or extrapolation (the data ranges from x = 0 to x = 5). Give the prediction to 1 decimal place.
