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.

5. Tyler has just moved into a new apartment and wants to purchase a new couch. He believes the mean price of a couch sold locally
may be greater than the mean price from an online retailer. He takes independent random samples of couches sold locally and online.
These samples consisted of 45 local store prices which had mean $670, and 42 online prices which had mean $650. Assume the
population of prices for each type of store are normally distributed with standard deviation $52. Test the claim that the mean price
of couches sold locally is greater than the mean price online using a 10% level of significance. Let u, be the mean price locally.
a. Write the hypotheses.
b. Identify sample statistics and given values symbollicaly.
Use your TI83/84 to find the TV. Do you use 2-SampZTest or 2-SampT
Test? Explain the reason for your choice.
d. Find the p-value and write in decimal form
(4 dec places) and as a percent.
C.
e. P-value Method.
Circle the correct statement.
f. Traditional Method.
Based on part e, circle the correct statement,
p-value Sa
p-value > a
