Note from the author:
Directions:
0) Make sure you've turned in your study guide.
On your desk - paper, pencil, calculator
On your browser - this test, Desmos links below.
In your backpack - phones, electronics, notes.
1) Take the test. If you're struggling, come back to the directions and formulae. Give it your best shot, but keep moving through the questions.
2) Some questions allow you to show your work. For these, just type what steps you took to get your answer. I may be able to give you partial credit if some of your steps are correct. You do NOT have to show your work.
3) Check your answers. Pay careful attention that you gave what the question was asking for. Check formatting especially.
4) Submit the test. Let me know if GoGuardian blocks you.
5) Close your Chromebook. Read, draw, or work on paper schoolwork quietly.
Desmos - Graphing
Desmos - Scientific Calculator
Mean and Standard Deviation Calculator.
\sigma = standard deviation (SD)
N = size of the data (number of values)
\mu = mean
x_{i} = data value
z = z-score
z = \frac{x-\mu}{\sigma}
margin of error (MOE) = \frac{2\sigma}{\sqrt{N}}
Hints:
- draw your bell curves and shade the big side
- for finding %s from the z-table, make sure you keep track of whether the question is comparing the data value to the population, or the population to the data value
- "or" should involve 3 numbers/subgroups; "and" should involve 1
- "given" = "|" = "out of", and this changes your denominator
