Answer:
The regression equation for the sample is
Y= 0.430x +0.214
Step-by-step explanation:
Using the regression formula;
a= (nSSXY - MX MY)/(nSSX -MX^2)
a= (20×43- 4×6)/(20×98 - (4^2))
a= 836/(1960-16)
a= 836/1944
a= 0.430
X bar= summation x / n =4/20= 0.2
Y bar= summation y / n =6/20 = 0.3
b= y bar - a xbar
b= 0.3 - 0.430(0.2)
b= 0.3- 0.086
b= 0.214
The regression equation
Y= ax + b
Y= 0.430x +0.214
