A study looked for a protein marker that might help predict active flare-ups in a particular chronic disease. A sample of 32 individuals with the disease had some blood taken to determine their disease status (active flare-up or inactive) and the relative abundance of the protein marker in their blood. We use logistic regression to model disease status as a function of relative abundance. Software gives the following information:
For Log Odds of Active/Inactive
$$\begin{array} { c c c }
\text { Term } & \text { Estimate } & \text { Std Error } \
\text { Intercept } & - 6.186 & 2.416 \
\text { Relative abundance } & 6.229 & 2.651
\end{array}$$ We want to know if the slope of the logistic regression model is significant. What is the value of the test statistic?
