Question

a researcher studied the relationship between the number of times a certain species of cricket will chirp in one minute and the temperature outside. her data is expressed in the scatter plot and line of best fit below. what is the meaning of the y - value on the line when x = 150?

Explanation:

In a scatter - plot with a line of best fit, the \(x\) - axis represents the number of chirps per minute and the \(y\) - axis represents the temperature in degrees Fahrenheit. The line of best fit is used to model the relationship between the two variables. When \(x = 150\) (where \(x\) is the number of chirps per minute), the \(y\) - value on the line of best fit is an estimate. Since the \(y\) - axis is temperature, this \(y\) - value estimates the temperature (in degrees Fahrenheit) when the cricket chirps 150 times in one minute.

Answer:

The \(y\) - value is the estimated temperature (in degrees Fahrenheit) when the cricket chirps 150 times in one minute.
