The following table gives the heat index (Heat Stress Index) as a function of the air temperature (Environ- mental Temperature) and the Relative Humidity. The heat index is measured in °F, the air temperature is measured in °F, and the relative humidity is measured in %. For this problem we will use the variables I (heat index), T (air temperature), and H (relative humidity). The table presents IT, H).
