They noted an initial 10-year increase in the population, followed by a 15-year decline in population. In the paper cited they found a curious relationship between the average weight of individual foraging workers and the population of the colony during the 15-year decline in population. Their data is given in the following table. x 7 32 45 120 y 50 62 73 79 A. Use power regression to find the best-fitting function to the data and the square of the correlation coefficient y ( x ) = 2 = 1 B. Find the derivative of y(x). y' ( x ) = Show My Work (Optional) ?
