The number of vacation days taken by the employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days. is this a case of sample standard deviation or population standard deviation? what are some differences between sample standard deviation and population standard deviation?

Step-by-step explanation:

Given that the number of vacation days taken by the employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days.

Since it is mentioned in general he employees of a company this is population std deviation.  If sample normally for a sample size of this is std deviation would be given.

Sample std deviation is the square root of variance of all the items from the sample mean.  Thus this is purely arrived from the sample observations taken.

Whereas population std deviation is square root of variance for all the entries in the population.

"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:

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
