1.Estimate the simple linear regression model and the logarithmic regression model for predicting time per unit using unit number as the predictor variable.

Note: Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.

2. Based on R², use the best-fitting model to predict the time that was required for the operator to build Unit 50.

Note: Round coefficient estimates to at least 4 decimal places and final answer to 2 decimal places.
