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 does the point $(132,73.9)$ represent?
answer
an expected temperature of $73.9^{circ} mathrm{f}$ when the cricket has
chirped 132 times.
actual temperature of $132^{circ} mathrm{f}$ when the cricket has chirped
73.9 times.
actual temperature of $73.9^{circ} mathrm{f}$ when the cricket has chirped
an expected temperature of $132^{circ} mathrm{f}$ when the cricket has
chirped 73.9 times.

Explanation:

Step1: Analyze scatter - plot data

In a scatter - plot, each point \((x,y)\) represents a relationship between two variables. Here, \(x\) is the number of chirps per minute and \(y\) is the temperature.

Step2: Interpret the coordinates of the point

For the point \((132,73.9)\), the \(x\) - value is \(132\) (chirps per minute) and the \(y\) - value is \(73.9\) (temperature in degrees Fahrenheit). This means when the cricket has chirped \(132\) times (the \(x\) - value, independent variable in the context of the scatter - plot), the actual temperature is \(73.9^{\circ}F\) (the \(y\) - value, dependent variable in the context of the scatter - plot).

Answer:

Actual temperature of \(73.9^{\circ}F\) when the cricket has chirped \(132\) times.
