Direction: Read, Analyze, and calculate what are required. 1- A biologist is comparing the intervals ( m seconds) between the mating calls of a certain species of tree frog and the surroundings temperature (tC). the following results were obtained. (15 Marks) a- Find the equation of the regression line of m on t giving your answer in the form m=a+bt (12 Marks) b- Use your regression line to estimate the time interval between mating calls when the surrounding temperature is 11 C
