Answer:
Y16 = 7(16) + 195.33 = 307.33
Y17 = 7(17) + 195.33 = 314.33
Y18 = 7(18) + 195.33 = 321.33
Y19 = 7(19) + 195.33 = 328.33
Explanation:
Period (x)
New accounts (Y)
The regression equation:
Y = mx + t
Y is the dependent variable
X is the independent variable
t point where trend line cuts through the x-axis
M is the gradient or slope
Using the regression calculator, the trend line for the data is :
Y = 7X + 195.33
Using the regression equation obtained :
Y16 = 7(16) + 195.33 = 307.33
Y17 = 7(17) + 195.33 = 314.33
Y18 = 7(18) + 195.33 = 321.33
Y19 = 7(19) + 195.33 = 328.33
