a. variable.

b. population.

c. statistic.

d. data.

Short answer

ThenumberXrepresentsthenumberofdaysthatLakeTahoeCommunityCollegestudentshavebeenabsent.

It's a variable that changes at random.

As a result, option A is right.

Step-by-step solution

Introduction

The number of days absent is a random number that is kept in X.

As a consequence, X is turned into a variable.

Explanation

$X$is a variable that represents the number of absences.

So $X$can be any integer and is assigned at random.

We didn't know its value before; all we knew was that it had to be a whole number because it represented the number of absences.
