Question

(b) choose whether each number described below is a parameter or a statistic for the math fair poll.

number	parameter	statistic
the average age of 22.3 years of the students who responded to the poll
the 83% of students who responded to the poll who want to transfer to a university

Explanation:

Step1: Define Parameter and Statistic

A parameter is a numerical measure that describes a population (the entire group of interest). A statistic is a numerical measure that describes a sample (a subset of the population).

Step2: Analyze Each Number

• For "The 60 students pursuing a math degree among all the current students at the community college": "All current students" is the population, so this is a parameter.
• For "The average age of 22.3 years of the students who responded to the poll": "Students who responded" is a sample (subset of all students), so this is a statistic.
• For "The 83% of students who responded to the poll who want to transfer to a university": "Students who responded" is a sample, so this is a statistic.

Answer:

Number	Parameter	Statistic
The average age of 22.3 years of the students who responded to the poll		✔️
The 83% of students who responded to the poll who want to transfer to a university		✔️
