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
SOLUTION:
Step 1:
In this question, we are given the following:
What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?
A. (-3.5, 1)
B. (1.5,-4)
C. (-4,1.5)
D. (1.-3.5)
Step 2:
The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

Answer:
3x² + 13x + 4
Step-by-step explanation:
3x³ - 2x² - 61x - 20
3x³ - 15x² + 13x² - 65x + 4x - 20
[3x²(x - 5) + 13x(x - 5) + 4(x - 5)]/(x-5)
3x² + 13x + 4
