Let x represent the full height of a certain species of tree. assume that x has a normal probability distribution with mean 36.4 ft and standard deviation 39.6 ft. you intend to measure a random sample of n=97 trees. the bell curve below represents the distibution of these sample means. the scale on the horizontal axis is the standard error of the sampling distribution. complete the following, correct to two decimal places.
μ¯x = σ¯x =

μ¯x = 36.4 ft

σ¯x = 4.02

Step-by-step explanation:

μ = 36.4 ft

σ = 39.6 ft

n = 97 trees

The mean of a sampling distribution will be the mean of the population/probability distribution. So in this example, it would be 36.4 feet.

μ¯x = μ = 36.4 ft

The standard deviation of the sampling distribution, what is also referred to as standard error, is the standard deviation of the population/probability distribution divided by the square root of the sample size (n). So in this example, it would be 39.6 divided by the square root of 97:

σ¯x = σ / √n   ⇒   σ¯x = 39.6 / √97 = 4.02

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

"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).
