The scatter plot shows the number of text messages sent per day versus age (in years) of the smartphone user. The least squares regression equation is:

Predicted Number of Text Messages Sent = 60 – 0.8 • Age

Use the drop-down menus to complete the statements below about what this linear model tells you about text messages sent by smartphone users.

Plz help it is worth 25 points

find the answers in the explanation.

Step-by-step explanation:

Given that the predicted Number of Text Messages Sent = 60 – 0.8 • Age

Where the slope = - 0.8

The intercept = 60

1) the slope of the least regression line is -0.8

2.) The unit of the slope of the line is text per year

3.) Therefore, the slope of the line tells you that for every year older the smart phone user is, you can expect a typical average in text messages sent of - 0.8

4.) The y - intercept of the least square regression line is 60

5.) The unit of the y - intercept of the line are text sent

6.) The y - intercept of the line tells you the starting point. The first number of text messages sent.

step-by-step explanation:

should you really be posting this isn't math boi.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
