c$)[5]$ Let us consider the following toy example database $($Table $2)$ containing patients' name, age,

hemoglobin and random sugar information. We consider an interactive database query setting

in which the sanitizer accepts queries and computes $lon-$differentially private answers using the

Laplace mechanism where $lon=0\mathrm{.}7.$ Compute an $lon-$differentially private answer for the following

query:

What is the average hemoglobin value of the patients in the database?
