Suppose you want to find the average household income in America. So you pick 10 households from each state (a total of 500 households) and find their income. What is the population? What is the parameter you want to find?

Step-by-step explanation:

The purpose of the experiment is to find the average or mean amount of household income in America.

Household Income simply means the total income of a household - which is the sum of income earned by each member of the household. This study aims to find the average of this household, across the Americas.

For your analysis, you pick 10 households from each state of the country (or continent). A total of 500 households implies 500/10 = 50 states

WHAT IS THE POPULATION?

The population in this study is:  the total population of American households OR the total number of households in America. The sample on the other hand, is the 500 households directly involved in the study.

WHAT IS THE PARAMETER YOU WISH TO FIND?

The parameter you wish to find is:  mean (or average) household income in America.

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
