An important advance in ecological research is the Theory of Island Biogeography, which demonstrates a relationship between the size of islands and the number of species of different amphibians that can be found in the islands. The scatterplot of number of species versus island area (in thousands of square miles) is nonlinear. The graphs below show the results of two different transformations of the data. Model I plots the square of the number of species against area. Model II plots the square root of the number of species against area. Linear regression analyses are provided below. Model I: (Number of Species)² vs. Area Model II: /Number of species vs. Area 8000 10 7000 cies)
Use the data analysis toolpak regression analysis to find the equation for the linear function that best fits this data. Round both numbers to two decimal places. Write your final answer in a form of an equation y = b0 + bx(x)Note: You will need to 'transpose' your data before running your regression to ensure you are working with column-oriented data. x 1 2 3 4 5 6 y 101 120 130 158 175 202

Flying twice as farA flight from Los Angeles to ABQ is about 2 hours but is 670.2 miles.A flight from San Jose to Chicago is 4 hours but is 1859.0 miles.Can anyone explain why the travel time from San Jose to Chicago is notlonger and closer to 5.75 hours?If the distance increase by 2, shouldnt the time increase by a factorof 2 as well?1. Write a linear model for this question. Takeoff and landing will take a fixed amount of time. Actualtravel in the air will take time proportional to the distance traveled. Think about which of thevariables (time and distance) is the independent variable, and identify the slope and intercept withtheir units.2. Use the data in the quotation to estimate the two constants in your linear model.
