A botanist is studying a newly identified soybean disease. The botanist collected soil samples from all of the

soybean fields in randomly selected states to see if there were significant differences the sulfur levels in fields with

and without the disease.

1. What is the population?

2. What is the sample?

3. What is the variable of interest?

4. How was the sample selected?

5. What method was used to collect the data?

6. Is the variable qualitative or quantitative?

7. Is the variable continuous or discrete?

1. What is the population?

All soybean fields in randomly selected states from which he collected soil samples

2. What is the sample?

All soil samples of soybean fields.

3. What is the variable of interest?

Amount of significant differences of the sulfur levels in fields with  and without the disease.

4. How was the sample selected?

The sample was selected  by using simple random sampling method.

5. What method was used to collect the data?

As he collected all soil samples to check the significant differences the sulfur levels in fields with and without the disease. To check sulfur level requires experiment, so he used experimental method to collect data.

6. Is the variable qualitative or quantitative?

The variable is quantitative.

7. Is the variable continuous or discrete?

the variable is continuous because sulfur level can take any value i.e. integer or decimal thus it is continuous
