Question

Birds' nests are always in danger from predators. If there are other nests close by, the chances of predators finding the nest increase. The table shows the probability of a nest being found by predators and the distance to the nearest neighboring nest. Distance to nearest neighbor (meters) 20 40 60 80 100 Probability of predators (%) 47 34 32 17 1.5 a. Plot the data and draw a line of best fit through the data points. Does it look like someone made an error? Ignoring the incorrect data point, draw a line of best fit through the other points. b. Use the regression line to estimate the probability of predators finding a nest if its nearest neighbor is 30 meters away. % c. If the probability of predators finding a nest is 25%, how far away is its nearest neighbor? meters d. What is the probability of predators finding a nest if its nearest neighbor is 130 meters away? % Is your answer reasonable? Select an answer
