To examine the linear correlation between adult age and weight, data was collected from 8 adults. See the
table below.

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 Even if the correlation is found to be statistically significant, that does not necessarily mean that
changes in x cause changes in y
O If the correlation is found to be statistically significant, that means that changes in x cause changes
in y
The hypotheses are:
O Ho:r = 0; Ha:r#0
O Ho:r < 0; Ha:r> 0
O Ho:p = 0; Ha:p+ 0
O Ho:p 2 0; Ha:p<0
O Ho:p < 0; Ha:p> 0
O Ho:r > 0; Ha:r <0
