Question A
Equation of the least square regression line:
We are given that: 𝑥 ̅ = 3.524, 𝑆𝑥 = 2.116, 𝑦 ̅ = 83.333, 𝑆𝑦 = 6.827 and 𝑟 = −0.328
The general equation for the least square method is summarized as 𝑦 ̅ = 𝑥 ̅ ∗ 𝑏1 + 𝑏0
Therefore, from the information provided we can re-write it as:
✓ 𝑏1 (slope)= 𝑟 ∗
