Kenneth is studying the relationship between the time spent exercising per day and the time spent outside per day. Data were collected ranging from 20 minutes to 90 minutes per day exercising.
The line of best fit for the data is given below. Assume the line of best fit is significant and there is a strong linear relationship between the variables.
y= 0.13x + 40.5
Answer the following (each is equally weighted):
1. Identify the explanatory and response variables (make sure your answer is related to the application and not just in terms of x and y).
2. According to the line of best fit, what would be the predicted number of minutes spent outside for someone who spent 70 minutes exercising?
3. Would it be appropriate to use this model to predict the number of minutes spent outside for someone who spent 0 minutes exercising? Why or why not (remember to include appropriate terminology).
