a) What is the best model for this data? O Linear O Exponential Logistic Parabolic Periodic b) Use the tool above to create an appropriate model for the data. Enter the equation for your model using a to indicate the temperature in degrees Fahrenheit and y to indicate the number of cricket chirps per 15 seconds. Your model will be used to assess your response to part d) below. c) What is the R² value of the correct model for this data? You may round your answer to four decimal places. d) Use your model to estimate the number of cricket chirps per 15 seconds if the temperature were 59° F. You may round your answer to two decimal places. chirps
e) Should the estimated value you input in part d) be trusted? Why or why not? BIUE = 7² X 2
