Looking at the data, does this rabbit growth look linear, quadratic, or exponential? Explain your answer. (1 point)2. Make a scatterplot for the data. (2 points)3. Looking at the scatterplot, which regression model do you think fits the data? Explain your answer. (1 point)4. Using a graphing calculator, find the quadratic regression equation for the rabbit data. (2 points: 1 point for identifying constants, 1 for the equation)5. Using the quadratic regression equation from question 4, predict the number of rabbits in year 70.(2 points: 1 point for setting up the correct equation, 1 for simplifying)6. Using a graphing calculator, find the exponential regression equation for the rabbit data. (2 points: 1 point for identifying the constants, 1 for the equation)7. Using the exponential regression equation from question 6, predict the number of rabbits in year 70. (2 points: 1 point for setting up the correct equation, 1 for simplifying)8. Compare the predicted number of rabbits for year 70 using the quadratic model (question 5) with the predicted number using the exponential model (question 7). Which prediction is larger? (1 point)9. Is it reasonable to use this data set to predict the hypothetical number of rabbits for year 70? Explain. (1 point)Making a Decision10. These graphs show the scatterplot with the quadratic regression equation and the exponential regression equation.a) Which do you think is a better fit? Why? (2 points: 1 point for choice, 1 point for explanation)b) How does your answer to part (a) compare with your guess about the best model in question 1? Was your initial choice correct? (1 point)Analyze Your Results11. The video says there were an estimated 10 billion rabbits in Australia after 70 years.a) How does your predicted number of rabbits for the hypothetical population compare with the actual rabbit population in Australia in year 70? (1 point)b) Why do you think the rabbit population in Australia can grow so large? (1 point)c) What are some factors that might prevent a rabbit population from growing infinitely large? (1 point)PROMPTRabbits are cute, aren't they? [An image of a rabbit appears.] But they can have lots of cute babies, and it's not long before the babies start having babies . . .[A green image of Australia appears.]In 1859, an Australian had 24 wild rabbits shipped to the land down under. [Small rabbits begin to pop up on the image of Australia and cover it entirely.] Within 70 years, there were an estimated 10 billion rabbits in Australia. That's billion . . . with a B. It's an ecological disaster they're still dealing with.So, how do we model growth like this mathematically? Here's some hypothetical data that grow a lot like the Australian rabbit population did. [A table showing the population of rabbits per year is shown]. The rabbit population is getting larger and larger, but is this growth linear? Or would a different model work better?
