In the summer, humidity interacts with the outdoor temperature, making a person feel hotter due to a reduced heat loss from the skin caused by higher humidity. The temperature-humidity index, T., is what the temperature would have to be with no humidity in order to give the same heat effect. One index often used is given byT = 1.98T - 1.09(1 - H)(T - 58) - 56.9. where Tis the air temperature, in degrees Fahrenheit, and H is the relative humidity, expressed as a decimal, Find the temperature-humidity index if T = 80 and H =58% The temperature-humidity index at 80" and 58% humidity is (Round to one decimal place as needed. )
