As part of a science project, Andy surveys several students in his class to determine their energy levels throughout the day. He asks the students to rate their energy level on a scale from 1 to 10, where 10 is the highest energy level possible and 1 is the lowest energy level possible. Andy then finds the average energy level for the class for each hour after the school day begins until the end of the day. He graphs his data as shown below.

Answer:

if we are doing the same thing it should be D-Andy’s study shows neither correlation nor causation.

Step-by-step explanation:

The average energy of the class after a different number of hours is given below.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

From the graph,

We can make two ordered pairs (x, y).

Where y = average energy level and x = the number of hours.

Now,

From the graph, we see that,

The average energy after 1 hour = 7

The average energy after 2 hours = 8

The average energy after 3 hours = 5

The average energy after 4 hours = 5

The average energy after 5 hours = 4

The average energy after 6 hours = 5

The average energy after 7 hours = 3

Thus,

The average energy of the class after a different number of hours is given above.
