At a mortgage company, 60% of calls are answered by an attendant. the remaining 40% of callers leave their phone numbers. of these 40%, 75% receive a return phone call the same day. the remaining 25% receive a return call the next day. of those who initially spoke to an attendant, 80% will apply for a mortgage. of those who received a return call the same day, 60% will apply. of those who received a return call the next day, 40% will apply. calculate the probability that a person initially spoke to an attendant, given that he or she applied for a mortgage.

  24/35, about 69%

Step-by-step explanation:

The data given can be put into a 2-way table (attached). It shows that 0.48 of all calls were answered and resulted in a mortgage application. Altogether, 0.70 of all calls resulted in a mortgage application. Thus the conditional probability of interest is ...

  p(spoke to attendant | applied for a mortgage) = p(spoke & applied)/p(applied)

  = 0.48/0.70 = 24/35 ≈ 69%

"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).
