a perfect negative
linear correlation.
Interpret the correlation. Choose the correct answer below.
A.
As companies' earnings per share increase, their dividends per share tend to decrease.
B.
Based on the correlation, there does not appear to be a linear relationship between companies' earnings per share and their dividends per share.
C.
Based on the correlation, there does not appear to be any relationship between companies' earnings per share and their dividends per share.
D.
As companies' earnings per share increase, their dividends per share tend to increase.
E.
Increases in companies' earnings per share cause their dividends per share to decrease.
F.
Increases in companies' earnings per share cause their dividends per share to increase.
(d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the correlation coefficient. Let
alphaαequals=0.01.
The critical value is
nothing.
Therefore, there

there is no correlation
there is a significant linear correlation
between companies' earnings per share and their dividends per share.
b)
(c) Describe the type of correlation, if any, and interpret the correlation in the context of the data.
There is no
linear correlation.
d)
Since, we know that
Degree of freedom (df) can be found out by n-2, where n is number of data points
df = n-2
df = 6-2
df = 4
critical value @ (df = 4 and \alpha = 0.01) = 0.917
Since, r = 0.069 is between -0.917 and 0.917. Therefore, r is not significant
Therefore, there is not sufficient evidence at the there is no correlation
between companies' earnings per share and their dividends per share.
