Answer:
a) Strong and Positive
b) 0.9995
Step-by-step explanation:
Here, we want to get the correlation type between the width and length
As we can see, as the width is increasing, the length is also increasing
What this mean is that we have a positive correlation
Now, we need to know if the correlation is strong or weak
Looking at the data values, we can see that while width is increasing by about 0.5 , length is increasing by about 0.7. These are very similar values
What this mean is that the correlation is also strong
Thus, we have it that the correlation is strong and positive
We can obtain the correlation coefficient value from the r-squared value
We can get this by plotting the points and fixing a line through as shown below:
From what we have on the plot:
the correlation coefficient is 0.9995
