Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1,4) and (x₂, y₂ ) = (- 5, 3)
d = 
= 
= 
= 
≈4.12 ( to 2 dec. places )
To find the midpoint use the midpoint formula
[0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]
Using the same points as above then
midpoint = [0.5(- 1- 5), 0.5(4 + 3 ) ] = [0.5(- 6), 0.5(7) ] = (- 3, 3.5 )
Lets use this set of data as an example:
2,2,3,3,3,3,4,4,5
Median is the data number that is in the middle of all of the numbers when arranged from least to greatest.
The median would be 3 since its in the middle. THINK: Median=Medium
Range is the highest number minus the lowest number. This is easy.
5-2=3
So the range is 3.
The mode is the number that you see the most often. 3 is the most since there are four 3s. There can be more than one mode or even no mode. THINK: Mode=Most
The mean is all of the numbers added together and then divided by the number of numbers.
2+2+3+3+3+3+4+4+5= 29
29 divided by 9 = 3.2222222222(repeated)
The mean can also be called the average.
I hope this helps!!!

Kindly check explanation
Step-by-step explanation:
The power of a test simply gives the probability of Rejecting the Null hypothesis, H0 in a statistical analysis given that the the alternative hypothesis, H1 for the study is true. Hence, the power of a test can be referred to as the probability of a true positive outcome in an experiment.
Using this definition, a power of 90% simply means that ; there is a 90% probability that the a Pvalue less Than the α - value of an experiment is obtained if there is truly a significant difference. Hence, a 90% chance of Rejecting the Null hypothesis if truly the alternative hypothesis is true.
