Answer:

strong negative linear correlation

Explanation:

Correlation coefficient is used in statistics to describe a <u>relationship between two variables</u>. A <u>negative </u>correlation describes the extent to which two variables move in <u>opposite directions</u> i.e. an increase in a variable is associated with a decrease in the other variable.  

Correlation coefficient is between -1 and 1.

-1 shows a perfect, linear negative correlation, and 1 shows a perfect, linear positive correlation.

In this example, <u>-90 shows a strong negative correlation</u>.

Packaging and hygiene paper- Packaging paper is a type of paper that is used to wrap things and food, such as snacks, oily foods, bags, etc. Hygiene paper is used daily in order to enjoy a comfortable life. Examples of this are kitchen towel, wipes, toilet paper, tissue paper, etc.

Technological Advancement- This refers to producing the same product with lower use of resources.  

Yes, it's true that technological advancement has decreased the usage of printing and writing paper. This is also because many people are already using high-tech electronic devices such as laptops and smartphones. It becomes rare to communicate or to submit one's work using paper.

<em>However, the number of people who are using packaging and hygiene paper has been increasing. This explains the increase in the total number of paper users from 92 million to 208 million in the last 20 years.</em>
