Question:

The following data represent the weight-lifting results from the 1976 Olympics.

Bodyweight class (lb) Flyweight Bantamweight Featherweight Max. weight 114.5 123.5 132.5 149.0 165.5

In Problems 6-12, construct a scatterplot of the given data. Is there a trend in the data? Are any of the data points outliers? Construct a divided difference table. Is smoothing with a low-order polynomial appropriate? If so, choose an appropriate polynomial and  fit using the least-squares criterion of best fit. Analyze the goodness of fit by examining appropriate indicators and graphing the model, the data points, and the deviations.
