Answer:
correlation between variables (r) = 0.959 and this signifies a positive relationship between the variables
Explanation:
A) Determine the correlation between the two variables
we have to apply simple Linear regression ( least square method )
attached below is the table
Regression equation ( y ) = a + bx
y = dependent variable ( mower )
x = independent variable ( fertilizer)
a = intercept point ( y axis and regression line )
b = slope ( regression line )
From the attached table
N = 14 , Σ x = 22.8,
Σy = 131, Σy^2 = 1269,
Σx^2 = 38.18, (Σx)^2 = 519.84
Σxy = 219.8, (Σy)^2 = 17161
correlation between variables (r) = 0.959 and this signifies a positive relationship between the variables
