Menso is an organisation for people with high intelligence quotients (iqs). menso is investigating the average iq of primary school students to determine whether its entry requirements should be altered for younger people. a sample of 55 primary school students have been randomly selected from schools throughout the country. the sample mean iq of those students was calculated as 99. it is known that the population standard deviation of the iqs of all people is 10. it is assumed that this standard deviation will also apply specifically to the iqs of the primary school students.

"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).

the answer is 11.2 (i know i’m late)
