(c) using the line of best fit, we would predict that a student texting for 5 hours would exercise for approximately choose one

Answer

Explanation:

Step1: Analyze scatter - plot trend

As we can see from the scatter - plot, as the time spent texting increases, the time spent exercising decreases.

Step2: Determine correlation type

Since the variables move in opposite directions, there is a negative correlation between time spent texting and time spent exercising.

Step3: Predict value using line of best - fit

Locate (x = 5) on the (x) - axis (time spent texting). Then, find the corresponding (y) - value (time spent exercising) on the line of best - fit. By visual inspection, when (x = 5), (y\approx6).

Answer:

(a) Decrease (b) Negative (c) 6 hours
