Answer:
Correlation is a measure of linear relationship.
Step-by-step explanation:
We are given that a correlation of 0.793 was found between the items answered and the mean score in a test.
- Correlation helps us to to know how to variables are related to each other.
- It is a statistical technique that help us to know type of relation between two variable. It may be a direct relation or a inverse relation.
- In other word, correlation is basically a measure of linear relationship between two variables.
- The correlation ranges from -1 to 1. A correlation between 0.7 and 1 is considered to be a strong correlation.
- A correlation of 0.793 means that there is a strong linear relationship between the two variables.
- Yes, there is a linear relationship between the number of questions answered and the mean score of test.
- So, it can be said as the number of questions answered increases, the mean score increases as well.

Answer:
16.9%
Step-by-step explanation:
Given data
Initial populatation= 4164
Final population= 3460
Percent decrease= initial-final/initial*100
Percent decrease= 4164-3460/4164*100
Percent decrease= 704/4164*100
Percent decrease= 0.1690*100
Percent decrease= 16.9%
Hence the decrease is 16.9%
