Answer:
Step-by-step explanation:
- The Z-score allows you to decide if your sample is different from the population mean. In order to use z, you must know four things:
- The population mean.
- The population standard deviation.
- The sample mean.
- The sample size.
- Usually in stats, you don’t know anything about a population, so instead of a Z score you use a T-Test with a T Statistic.
- The major difference between using a Z score and a T statistic is that you have to estimate the population standard deviation. The T test is also used if you have a small sample size (less than 30).

Answer:
The answer to your question is VW = 2.2
Step-by-step explanation:
Data
angle = 63°
hypotenuse = ?
adjacent side = 1
Process
To solve this problem use trigonometric functions, the trigonometric function that relates the adjacent side and the hypotenuse is cosine.
cos α = 
solve for hypotenuse
hypotenuse = 
Substitution
hypotenuse = 
Simplification
hypotenuse = 
Result
hypotenuse = 2.2
