Answer with Step-by-step explanation:
Since we have given that
Number of students = 100
Mean = 21.3 years
In what way are descriptive statistics involved in this example?
As we know that descriptive statistics gives information that explains the data is specific manner and while measuring the mean age of the 100 students she needs to collect data by asking their age from them.
In what way are inferential statistics involved?
As we know that inferential statistics form inferences about given populations using given data, so when she estimate the mean age of 100 students, she will use data of 100 students. So, she is using inferential statistics.
6x-6=8x
subtract 6x from both sides
-6=2x
divide both sides by 2
x= -3
Use the quadratic formula to get x = (3 - 2*sqrt(6))/3 or x = (3 + 2*sqrt(6))/3
