The exponential regression function for the scatterplot without outliers is f(t) = 85.8507(0.56049)ª. The coefficient of determination is 0.976. The exponential regression function for the scatterplot with outliers is f(t) = 71.4094(0.60228)*. The coefficient of determination is 0.740. Which regression function is more appropriate for the data?
