A sample of 50 patients that had a knee replaced by the doctor showed that only 34 of them returned to work within 3 months of the surgery. Test the doctor's claim at the 0.05 level of significance. 2) A researcher wants to determine what proportion of all high school students plans to attend community college upon graduating. He has no idea of what the sample proportion will be. How large of a sample is required in order to be 90% sure that the sample proportion is off by no more than 2%?

Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

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

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