Attitudes toward recycled products Exercise 19 gives data on the opinions of people who have and have not bought coffee filters made from recycled paper.

To see the relationship between opinion and experience with the product, find the conditional distributions of opinion (the response variable) for buyers and nonbuyers. What do you conclude?

Short Answer

Expert verified

Filter paper is thought to be of great quality by 55.56 percent of purchasers. And 44.3 percent of non-buyers believe that filter paper is of poor quality.

Step by step solution

The given data of who have and have not bought coffee filters made from recycled paper is:


Think the quality ofthe recycled productsis:

Concept

The distribution of a category variable is displayed using pie charts and bar graphs. Any set of quantities measured in the same units can be compared using bar graphs. It's a good idea to ask yourself, "What do I see?" when looking at any graph.

03

Calculation

For non-buyers of coffee filters made of recycled paper, the conditional distribution of opinion (the response variable) is as follows:

We can deduce from the above table of the conditional distribution of opinion (the response variable) for buyers and non-buyers of coffee filters made of recycled paper that the majority of people (55.546percent) who buy coffee filters made of the recycled paper believe the filter paper is of high quality. Furthermore, 44.3percent of non-buyers of coffee filters made of the recycled paper believe that the quality of filter paper is poor. As a result, 55.56percent of purchasers believe filter paper is of great quality. And 44.3percent of non-buyers believe that filter paper is of poor quality.

A survey was designed to study how business operations vary according to their size. Companies were classified as small, medium, or large. Questionnaires were sent to 200 randomly selected businesses of each size. Since not all questionnaires in a survey of this type are returned, researchers decided to investigate the relationship between the response rate and the size of the business. The data are given in the following two-ways

Which of the following conclusions seems to be supported by the data?

(a) There are more small companies than large companies in the survey.

(b) Small companies appear to have a higher response rate than medium or big companies.

(c) Exactly the same number of companies responded as didn’t respond.

(d) Small companies dislike larger companies.

(e) If we combined the medium and large companies, then their response rate would be equal to that of the small company

Electoral votes To become president of the United States, a candidate does not have to receive a majority of the popular vote. The candidate does have to win a majority of the 538 electoral votes that are cast in the Electoral College. Here is a stemplot of the number of electoral votes for each of the 50 states and the District of Columbia.

(a) Make a boxplot of these data by hand. Be sure to check for outliers.

(b) Which measure of center and spread would you use to summarize the distribution—the mean and standard deviation or the median and IQR? Justify your answer.
