To graph: The
a.
Answer to Problem 1CYU
Explanation of Solution
Given information:
The table is mentioned below.
Formula:
We take x axis as no. of friends and y axis as no. of text messages.
Consider the table as mentioned above.
Recall that we take x axis as no. of friends and y axis asno. of text messages.
Therefore the scatter plot is mentioned below.
b.
To write: The conclusion about the relationship in the scatter plot.
b.
Answer to Problem 1CYU
The conclusion we get from scatter plot is no relationship.
Explanation of Solution
Given information:
The scatter plot is mentioned above.
Formula:
We use the scatter plot graph mentioned above.
Consider the scatter plot as mentioned above.
Recall that the x axis represents no. of friends and y axis represents no. of text messages.
Here from the scatter plot we observed that as the no. of friends increases the no. of text messages first decreases and then decreases and again increases.
Therefore the graph shows the no relationship.
