Question

y̅ = 9
x̅ = 5
b = 1.61
a = y̅ - bx̅
use the values and formulas above to calculate the y - intercept.
1.8
2.45
0.2
1.05
0.95

Explanation:

Step1: Substitute given values

Given $\bar{y}=9$, $\bar{x}=5$, $b = 1.61$ into $a=\bar{y}-b\bar{x}$. So $a=9 - 1.61\times5$.

Step2: Calculate the product

First, calculate $1.61\times5 = 8.05$.

Step3: Calculate the result

Then, $a=9 - 8.05=0.95$.

Answer:

0.95
