A research center claims that at least 23% of adults in a certain country think that their taxes will be audited. In a random sample of 1200 adults in that country in a recent year, 20% say they are concerned that their taxes will be audited. At a = 0.10, is there enough evidence to reject the center's claim?

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
