To determine

The type of data.

02

Explanation

Quantitative variables are those that can be stated numerically. We regard this variable to be quantitative because the quantity of packages is given numerically. Discrete variables are those that can only be stated in whole numbers rather than decimals.

Because package numbers are always expressed in whole numbers, there can only be 5 or 6 packages, not 5.5 packages. It isn't doable in practise. As a result, the quantity of software packages is a discrete quantitative variable.
