To determine

The difference in humidities required to raise the apparent temperature from $87°\text{ F to 102}°\text{ F}$ at an actual temperature of $80°\text{ F}$. The data that show the apparent temperature for various actual temperatures and relative humidifies are tabulated below:

ACTUAL TEMPERATURE $\left(°\text{F}\right)$	RELATIVE HUMIDITY
		10%	20%	30%	40%	50%	60%	70%	80%	90%	100%
		APPARENT TEMPERATURE $\left(°\text{F}\right)$
