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.

**Understanding Hypothesis Testing in the Context of Left-Handedness**

It is believed that 11% of all Americans are left-handed. A college needs to determine how many left-handed desks to place in the large lecture halls being constructed on its campus. In a random sample of 200 students from that college, whether or not a student was left-handed was recorded for each student. The college wants to know if the data provide enough evidence to show that students at this college have a lower percentage of left-handers than the general American population. This involves stating the random variable, population parameter, and hypotheses, and understanding Type I and Type II errors in this context.

### a) Random Variable

- **Symbol for the random variable:** $ \hat{p} $
- **Contextual wording for the random variable:** The proportion of left-handed students in the sample of 200 students.

### b) Population Parameter

- **Symbol for the parameter:** $ p $
- **Contextual wording for the parameter:** The proportion of all students at the college who are left-handed.

### c) Null and Alternative Hypotheses

- **Null Hypothesis ($ H_0 $):** $ p = 0.11 $
- The proportion of left-handed students at the college is equal to 11%, the national average.
- **Alternative Hypothesis ($ H_A $):** $ p < 0.11 $
- The proportion of left-handed students at the college is less than 11%.

### d) Type I Error

- **Definition Context:** A Type I error would occur if the college concludes that the proportion of left-handed students is lower than 11% when, in fact, it is not.

### e) Type II Error

- **Definition Context:** A Type II error would occur if the college fails to conclude that the proportion of left-handed students is lower than 11% when, in fact, it is lower.

Understanding these statistical terms helps in making informed decisions based on the hypothesis testing results.
