You have calculated the following power model and associated

You have calculated the following power model and associated unit space values:

Cost = 122.31+126.80 (Weight)   SE = 12.69

n =7, Summation of (Y– Yhat)2 = 1285

Answer selections are:

Power equation because it has a higher standard error than the linear model.
   Linear equation because it has a higher standard error than the power model.
   Power equation because it has a lower standard error than the linear model.
   Linear equation because it has a lower standard error than the power model.

Solution

Linear equation because it has a higher standard error than the power model.

You have calculated the following power model and associated unit space values: Cost = 122.31+126.80 (Weight) SE = 12.69 n =7, Summation of (Y– Yhat)2 = 1285 An
