From the given scatter plot, the pair of values of (x, y) are distributed from left top to right down side. That is, the values are distributed downward side. Hence, the correlation should be negative. Moreover, the values are not lies one the straight line. Hence, the correlation should be nearer to -1 not exactly equal to -1.Hence, the r value is -0.8 Correct option r=-0.8

Angles

In mathematics, angles constitute a very important part. Just like the concept of lines, an angle is a necessary figure that is used for measurement. How do you define its formation? It is formed when two or more lines meet at a point. The point at which two or more lines meet is known as the vertex. When the lines get inclined at this point, they do form various angles. Angles are measured from the vertex in terms of degrees.

Question

**Consider the following scatterplot:**

The scatterplot presents data with "Variable Y" on the vertical axis and "Variable X" on the horizontal axis. The plot consists of several data points that appear to be randomly scattered across the graph without forming a clear linear pattern.

**Question:**
What is your best estimate of the correlation coefficient shown above?

**Options:**
- ○ +1.0
- ○ +0.8
- ○ 0.0
- ○ -0.8
- ○ -1.0

The correct estimate would likely be close to 0.0, indicating no apparent correlation between Variable X and Variable Y.
