• Question 16
>
In soccer, it seems reasonable to assume that the more shots a team takes, the more goals they will score.
A random sample of 25 soccer matches found that the linear correlation coefficient between shots taken
and goals scored was 0.3.
Does this result suggest that the correlation is statistically significant? Use a = 0.01.
1. Select the correct statement:
O If the correlation is found to be statistically significant, that means that changes in x cause changes
in y
O Even if the correlation is found to be statistically significant, that does not necessarily mean that
changes in x cause changes in y
The hypotheses are:
O Ho:p = 0; Ha:p# 0
O Ho:p 2 0; Ha:p < 0
O Ho:r > 0; Ha:r < 0
O Ho:r < 0; Ha:r > 0
O Ho:p<0; Ha:p> 0
O Ho:r = 0; Ha:r # 0
