Music some students do homework with music playing in their headphones. (anyone come to mind? ) some researchers want to see if people can work as effectively with as without distrac-tion. the researchers will time some volunteers to see how long it takes them to complete some relatively easy crossword puz-zles. during some of the trials, the room will be quiet; during other trials in the same room, subjects will wear headphones and listen to a pandora channel.
a) design an experiment that will require a two-sample t-procedure to analyze the results.
b) design an experiment that will require a matched-pairs t-procedure to analyze the results.
c) which experiment would you consider the stronger design? why?

"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).

step-by-step explanation:

answer: 5

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
