Step 1
Note: We’ll answer the first question since the exact one wasn’t specified. Please submit a new question specifying the one you’d like answered.
Solution:
Given:
X034512Y826912
Equation of regression line is,
Y=a+bX
where, a=(y)(x2)x(xy)n(x2)(x)2
b=n(xy)(x)(y)n(x2)(x)2
Step 2
Table for calculation:
XYXYX2080032694624165945251212144144=24=37=219=194
a=37×19424×2195×194242
=4.88
and b=5×21924×375×194242
=0.525
Therefore regression equation is,
Y=4.88+0.525X
Answer : Equation of regression line is Y=4.88+0.525X.
