Answer

Explanation:

Step1: Analyze scatter - plot trend

As we can see from the scatter - plot, as the value of the x - variable (time spent texting) increases, the value of the y - variable (time spent exercising) decreases.

Step2: Determine correlation type

Since an increase in one variable is associated with a decrease in the other variable, there is a negative correlation.

Step3: Use line of best - fit for prediction

Locate x = 6 on the x - axis of the scatter - plot. Then, find the corresponding y - value on the line of best - fit. By visual inspection, when x = 6, y is approximately 5.

Answer:

(a) decrease (b) negative (c) 5 hours
