1. A healthy human body temperature is 37.0 °C. Eight people were medically examined and the difference in their body temperature (°C), from 37.0 °C, was recorded. Their heartbeat (beats per minute) was also recorded. Temperature difference from 37°C (x) -0.2 0.3 -0.3 -0.2 -0.1 0.2 0.5 Heartbeat (y) 63 77 70 74 65 78 79 86 This data can be modelled by the regression line with the equation y = ax + b. a. Write down the value of a and b. b. Explain what the gradient a represents.
