Which of the following gives a correct interpretation of s in this setting?

(a) For every 1°C increase in temperature, fish activity is predicted to increase by 4.785 units.

(b) The typical distance of the temperature readings from their mean is about 4.785°C.

(c) The typical distance of the activity level ratings from the least-squares line is about 4.785 units.

(d) The typical distance of the activity level readings from their mean is about 4.785.

(e) At a temperature of 0°C, this model predicts an activity level of 4.785.
