Does this result suggest that the correlation is statistically significant? Use a = 0.10.
Important Note: Round your value for r to three decimals before computing the STS. DO NOT use the built-
in LinRegTTest on a calculator because you might get marked wrong. When computing the P-value, use the
rounded STS.
1. Select the correct statement:
O lf the correlation is found to be statistically significant, that means that changes in æ 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
