Hey there!
We have:
4 students with 5 marks.
8 students with 6 marks.
10 students with 7 marks.
7 students with 8 marks.
13 students with 9 marks.
3 students with 10 marks.
Thus, the mean is: 
, or around 7.58 marks.
The median is the middle number and since we have 45 people, the middle number would be the 23rd. 4+8+10+1=23, Thus, 8 marks i s the median.
The mode is the most common score, which is 9.
The range is the range of all the values, which is from 5-10. Thus, giving us a range of 10-5, or 5.
Hope this helps :)
Answer:
The correct statement about the hemoglobin and myoglobin is as follows:
1. Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.
3. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron.
4. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.
5. Heme is composed of an organic protoporphyrin component and a metal atom.
6. Each iron atom can form six coordination bonds: One of these bonds is formed between iron and oxygen.
