Question

The following data was obtained by two fishermen visiting the lake.
Let x = length of a Northern Pike in inches and let y = weight in pounds.
Use your calculator to draw a scatter diagram.
Using the scatter diagram (no calculations), would you estimate the linear correlation coefficient to be positive, close to zero, or negative?

x (inches) 20 24 36 41 46
y (pounds) 2 4 12 15 20
Select one:
a. the linear correlation coefficient would be close to 0
b. the linear correlation coefficient would be negative
c. the linear correlation coefficient can not be found from the scatter plot
d. the linear correlation coefficient would be positive

Answer 1

Which do you believe it is?

Answer 2

I was thinking c or d, but I'm very confused with statistics

Answer 3

I believe C is the best choice

Answer 4

Ok, thank you!
