Answer:
3/10 or 0.3 or 30%
Step-by-step explanation:
Its 225/750 total students
We simplify this by dividing by 5
45/150
Divide by 5 again
9/30
Divide by 3
3/10
Answer:
t distribution behaves like standard normal distribution as the number of freedom increases.
Step-by-step explanation:
The question is missing. I will give a general information on t distribution.
t-distribution is used instead of normal distribution when the <em>sample size is small (usually smaller than 30) </em>or <em>population standard deviation is unknown</em>.
Degrees of freedom is the number of values in a sample that are free to vary. As the number of degrees of freedom for a t-distribution increases, the distribution looks more like normal distribution and follows the same characteristics.
Use PEMDAS to first simplify the equation
answer is: 128.8
