Lindsay created the table below showing the population of fruit flies over the last 10 weeks. She estimates that the population of fruit flies can be represented by the equation [math]y = 46x – 40[/math]. Using residuals, determine if her representation is a good estimate.
[list=1] [*]Find the estimated population at each [i]x[/i]-value. [*]Evaluate the equation at each value of [i]x[/i]. [*]Find the residuals by finding each difference between the observed population and estimated population. [*]Create a residual plot. [*]Analyze the residual plot to determine if the equation is a good estimate for the population.
