A company is criticized because only 18 of 49 executives at a local branch are women. The company explains that although this proportion is lower than it might wish, it's not a surprising value given that only 45% of all its employees are women. The company has more than 500 executives worldwide. Test an appropriate hypothesis and state the conclusion. Determine the hypotheses for this test. (The proportion of female executives in the entire company is denoted by p.) A. Upper H 0: pequals0.45 Upper H Subscript Upper A: pnot equals0.45 B.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
