Question

the scatter plot shows the time spent texting and the time spent exercising by each of 21 students last week. also shown is the line of best fit for the data. fill in the blanks below. (a) for these 21 students, as the time spent texting increases, the time spent exercising tends to select (b) for these 21 students, there is select correlation between time spent texting and time spent exercising. (c) using the line of best fit, we would predict that a student texting for 6 hours would exercise for approximately select

Explanation:

Step1: Analyze scatter - plot trend

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

Step2: Determine correlation type

Since the time spent exercising decreases as the time spent texting increases, there is a negative correlation.

Step3: Predict using line of best - fit

Locate x = 6 on the x - axis (time spent texting) on the line of best - fit and then find the corresponding y - value (time spent exercising). By observing the line of best - fit, when x = 6, y is approximately 5.

Answer:

(a) Decrease
(b) Negative
(c) 5 hours
