A wildlife management team studied the reproductiverates of deer in three tractsof a wildlife preserve.Each tract contained5 acres. In eachtract, the number offemales and thepercent of femalesthat had offspring thefollowing year wererecorded. The tableshows the results.(a) Use the data to create a system of linear equations.Then find the least squares regression parabola forthe data by solving the system.(b) Use a graphing utility to graph the parabola andthe data in the same viewing window.(c) Use the model to estimate the percent of femalesthat had offspring when there were 170 females.(d) Use the model to estimate the number of femaleswhen 40% of the females had offspring.
