29. What is the correct interpretation of the estimate of the slope coefficient 3₁? O We estimate that the mating song frequency of Hyla chrysoscelis increases on average by 2.331 notes/sec for every 1°C increase in habitat temperature. O We estimate that the mating song frequency of Hyla chrysoscelis increases on average by 8.243 notes/sec for every 1°C increase in habitat temperature. O We estimate that the mating song frequency of Hyla chrysoscelis decreases on average by 6.190 notes/sec for every 1°C increase in habitat temperature. O We estimate that the mating song frequency of Hyla chrysoscelis is expected to be 2.331 notes/sec for every 1°C increase in habitat temperature.

Question
Transcribed Image Text:Section H: Hyla chrysoscelis is a type of gray tree frog with a distinct mating call. Frogs are cold-blooded animals, and
their physiology is affected by variations in temperature. Researchers wanted to know if the mating song of Hyla
chrysoscelis is affected by the temperature of its natural habitat. They observed the mating song frequency (y in
notes/sec) and the habitat (x in °Celsius) of 20 Hyla chrysoscelis in the wild. We aim to express the relationship between
and y by using the simple linear regression model Yį = ßo + ß₁ x; + Eį.
