According to Equation 17.2, and as discussed in Chapter 16, holding relative humidity constant at a fixed value, each one-degree increase in temperature is associated with an estimated 0.88 more ice cream bars sold on average. This is true regardless of the value at which relative humidity is held constant. Likewise, holding temperature constant at a fixed value, each one-percentage increase in relative humidity is associated with an estimated 0.40 more ice cream bars sold on average regardless of the value at which temperature is held constant.
