Answer:
The mean is 561.40 ppm. The standard deviation is 29.15 ppm.
Step-by-step explanation:
We can calculate the mean and the standard deviation using the proportions of the population that are subjected to the different levels.
The mean can be calculated as
The standard deviation of the mean can be calculated in a similar way
The mean is 561.40 ppm. The standard deviation is 29.15 ppm.
So you can look at the first digit of each number: you have a 3, 2, 3. You know 2 is less than three. So 2,965,006 is the smallest number. You had two numbers where 3 was the first digit, so you look at the next number: a 5 and 2. 2 is smaller than 5, so 3,261,636 will be the next smallest.
Overall, least to greatest is:
2,965,006; 3,261,636; and finally 3,516,235 :)

ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.
EXPLANATION:
<em>1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell. </em>
Therefore, half of a plant cell's size is 0.000006325 m.
<em>2. We now compare the size of half of the plant cell to the size of the red blood cell.</em>
0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
