The emissivity of the human skin is 97.0 percent. Use 35.0 °C for the skin temperature and approximate the human body by a rectangular block with a height of 1.92 m, a width of 39.0 cm and a length of 28.5 cm. Calculate the power emitted by the human body. Tries 0/12 What is the wavelength of the peak in the spectral distribution for this temperature? Tries 0/12 Fortunately our environment radiates too. The human body absorbs this radiation with an absorbance of 97.0 percent, so we don't lose our internal energy so quickly. How much power do we absorb when we are in a room where the temperature is 26.0 °C? Tries 0/12 How much energy does our body lose in one second?

Researchers Hill and Barton used data from the 2004 Olympics to test whether one uniform color (red or blue) gave athletes a competitive advantage. In the sports of boxing tae kwon do, and wrestling, athletes are randomly assigned either a red or blue uniform. They found that out of 457 matches, the competitor in red won 248 times.

Let pi be the long-term probability that an Olympic match of boxing tae kwon do, or wrestling is won by the athlete wearing a red uniform. Then we want to test
