55.56%buyers have the opinion that the quality of filter paper is high. And 44.3% non-buyers of have the opinion that the quality of filter paper is low.

Explanation of Solution

Calculation:

Conditional distribution of opinion (the response variable) for non-buyers of coffee filters made of recycle paper is below:

Conditional Distribution Table for non-buyer of coffee filters of recycle paper
Opinion	Non Buyers
	Total No.	Percentage
Higher	29	$\frac{29}{97}\times 100$	29.9
The Same	25	$\frac{25}{97}\times 100$	25.8
Lower	43	$\frac{43}{97}\times 100$	44.3
Total	97		100

From the above table of conditional distribution of opinion (the response variable) for buyers and non-buyers of coffee filters made of recycle paper we conclude that most of the people (55.546%) who buy coffee filters made of recycles paper have the opinion that the quality of filter paper is high. And 44.3% of people who are non-buyers of coffee filters made of recycle paper have the opinion that the quality of filter paper is low.
