Test 1 - Requires Respondus LockDown Browser + Webcam

For the following test, the following formulas are given:

• \(\displaystyle \overline{x}=\frac{\sum x}{n}\)
• \(\displaystyle \mu=\frac{\sum x}{N}\)
• \(\displaystyle s=\sqrt{\frac{\sum\left(x-\overline{x}\right)^2}{n-1}}\)
• \(\displaystyle \sigma=\sqrt{\frac{\sum\left(x-\mu\right)^2}{N}}\)
• \(\displaystyle \textrm{CV}=\frac{s}{\overline{x}}\)
• \(\displaystyle \textrm{CV}=\frac{\sigma}{\mu}\)
• \(\displaystyle z=\frac{x-\overline{x}}{x}\)
• \(\displaystyle z=\frac{x-\mu}{\sigma}\)
