A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades In 2019, wind power accounted for 5 percent of all electricity generated in the United States The US Geological Survey compiled a database of over 53700 wind turbines in the country. Several variables measured for each wind turbine in the database are listed. Determine the type of data (quantitative or qualitative) recorded for each variable. (Note: A project consists of multiple wind turbines that form a single system.) Complete parts a through e. a. Turbine rotor swept area (measured in square meters) Choose the correct answer below A. The variable is qualitative because the data can be classified into multiple non-numerical categories B The variable is qualitative because the data cannot be measured on a naturally occurring numerical scale C. The variable is quantitative because the data can be measured on a naturally occurring numerical scale. D The variable is quantitative because the data are numerical values

Question

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades In 2019, wind power accounted for 5 percent of all electricity generated in the United States The US Geological Survey compiled a database of over 53700 wind turbines in the country. Several variables measured for each wind turbine in the database are listed. Determine the type of data (quantitative or qualitative) recorded for each variable. (Note: A project consists of multiple wind turbines that form a single system.) Complete parts a through e. a. Turbine rotor swept area (measured in square meters) Choose the correct answer below A. The variable is qualitative because the data can be classified into multiple non-numerical categories B The variable is qualitative because the data cannot be measured on a naturally occurring numerical scale C. The variable is quantitative because the data can be measured on a naturally occurring numerical scale. D The variable is quantitative because the data are numerical values

Answer 1

The correct answer is 'C'. The variable is quantitative because the data can be measured on a naturally occurring numerical scale.

Answer 2

## Step 1The problem is asking us to determine whether the given variable, which is the turbine rotor swept area, is qualitative or quantitative. ## Step 2Qualitative data is non-numerical and is used to describe things. This includes things like colors, names, labels, and other attributes that cannot be measured on a numerical scale.## Step 3On the other hand, quantitative data is numerical and can be measured on a numerical scale. This includes things like height, weight, temperature, and in this case, the turbine rotor swept area.## Step 4The turbine rotor swept area is measured in square meters, which is a numerical unit. This means that the data can be measured on a naturally occurring numerical scale.
