. Hylo chrysoscelis is a type of tree frog with a distinct mating call. Field biologists wanted to know if the temperature of its natural habitat affects the frog's mating call, so they sampled 23 frogs and measured the ground temperature where they sat and their mating call frequency. The correlation between ground temperature and mating call frequency was r = 0.?5. The ground temperatures had a mean of 211C and a standard deviation of 320C. The frequency of the mating calls bad a mean of 45.1 notesfsec and a standard deviation of 3.9 notesfsec. a. Assuming all relevant assumptions were met, find the OLS linear regression equation for predicting mating call frequency based on ground temperature. Write the whole equation and use variable names. (1 pt) b. Interpret the coefficient estimates (slopes) of your model in the context of the problem. (Ipt) c. If a frog was sitting on 30C ground and had call frequency of 52 notesz'sec. what is this frog's residual? (I or}
