To determine the residual for the observed data x = 7 and y = 70 in a power model, we need a power model equation.

A power model follows the form: y = a * x^b

To find the equation for the power model, we need more information or data points to perform a regression analysis.

Once we have the power model equation, we can substitute x = 7 and y = 70 into the equation to calculate the predicted value.

The residual is then calculated by subtracting the predicted value from the observed value:
Residual = Observed value - Predicted value

Since we don't have the power model equation or enough data points, we cannot determine the residual for the given observed data.
