Question 1 [Explained]
The table below presents data collected from a particular study, and this data is also plotted on a scatter plot below.
We aim to understand how the variable y depends on x by fitting a regression line. The equation for this regression line is given by y = ax + b, where a and b are constants belonging to the set of real numbers, R.
x | 3.3 | 6.9 | 11.9 | 13.4 | 17.8 | 19.6 | 21.8 | 25.3 |
y | 6.3 | 8.1 | 8.4 | 11.6 | 10.3 | 12.9 | 13.1 | 17.3 |
