Question: Construct a scatterplot of the given data. Is there a trend in the data? Are any of the data points outliers? Construct a divided dijference

Construct a scatterplot of the given data. Is there a trend in the data? Are any of the data points outliers? Construct a divided dijference 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.
