Marysya12 [62]

Answer:

C

Explanation:

Trees take up carbon dioxide from the atmosphere and reduce to make carbohydrates. This  is powered by the energy of the sun that is taped by chlorophyll pigments during photosynthesis. The energy is used to split water molecules into H+ and O2-. Then the following chemical reaction ensues;

6CO2 + 6H2O ------> C6H12O6 + 6O2

The brain volumes ​(cm cubed​) of 20 brains have a mean of 1116.2 cm cubed and a standard deviation of 127.7 cm cubed. Use the g
Shkiper50 [21]

Answer:

Yes

Explanation:

Range rule of thumb predicts the Range to be  a multiple of 4 of the standard deviation or to be four times  the standard deviation. Making the usual values equal to 2 standard deviations distanct of the mean of the data distribution.

In a given distribution with mean and standard deviation that is obtained, the usual values in mean (as seen in the attached image).

2*standard deviation and mean + 2*standard deviation.

If the data point is not up to the mean

- 2* standard deviation is taken to be significantly low.

If the data point is more than the mean

+ 2*standard deviation is taken to be significantly high.

Let's take the xbar to be the mean and s as standard deviaiton

Given,

mean, xbar = 1116.2

standard deviation, s =127.7

The range rule of thumb shows that the usual values are within 2 standard deviations from the mean

Lower boundary

      = xbar - 2s

       = 1116.2 - 2(127.7)

       = 860.8

Upper boundary

      = xbar + 2s

       = 1116.2 + 2(127.7)

       = 1371.6

We should note that 1411.6 is not between 860.8 and 1371.6, which connotes that 1411.6cm^3 is unusually high.
