Answer #1

1. Bring data in to excel sheet

2.Select both x and y variable and insert scatter plot chart. Select any data point in the excel and add trend line. In the format trend line option choose "Linear" and also select "Display an equation on chart"

Regression Equation: y = 49.7 -0.105x

Predict 27 years

y = 49.7 -0.105x

y =49.7-0.105*27 = 47
