To find the test statistic or z-score given sample number (n), sample mean (x), standard deviation (σ), and population mean (μ), we can use
Given that n = 36, x = 24.6, μ = 20, and σ = 12,
From this, we see that the test statistic is 2.3.
Answer: 2.3
The binomial factor of the equation 
is 3x-8.
<h3>What is a binomial factor?</h3>
The algebraic expression which contains only two terms is called binomial. It is a two-term polynomial. Also, it is called a sum or difference between two or more monomials.
Factoring binomials means breaking down a binomial expression into its simplest form.
Binomials are algebraic expressions with two terms.
The given binomial is;
The binomial is determined in the following steps given below.
Hence, the binomial factor of the equation is 3x-8.

1850 x 0.22 (decimal form of 22%) = 407. 407 plastic beads are on clearance.
Answer:
The standard notation would be 141.7
Step-by-step explanation:
The mean increases by 1.5 because every value is increased by 1.5, take this example.
{1, 3, 7, 9} has a mean of 5.
Add 1 to each value.
{2, 4, 8, 10} has a mean of 6.
Standard Deviation generally stays the same despite the change in values, because of it's equation is based on the mean and data values and the distance between them in the end do not change if ALL values in a data set increase/decrease by the same number.
