Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Number of donuts consumed in a month = y
Age = x
Regression equation obtained :
y=47-1.36x
Meaning of slope of the regression line ;
Comparing the regression equation obtained with the general equation of a linear regression line ;
y = mx + c; where m = slope of the regression line
Hence, the value of slope in the equation is = - 1.36
Thus, the slope can be interpreted as ; The number of donuts consumed in a month is expected to decrease by 1.36 for per(1) increase in age x of consumer.
