Answer:
Standard deviation of the population is 2.4
Step-by-step explanation:
Finishing times of 6 participants in 200 meter dash has been given as 27, 28, 27, 25, 24, 31.
We have to calculate the standard deviation of the population formed by these timings.
Formula of standard deviation is

where
= standard deviation
= mean of the data
n = number of scores in the sample
Mean of given data = 

= 
= 30
Now 
= 2.236 ≈ 2.24
Therefore, standard deviation of the given data is 2.24
Answer:
The answer would be y = -1/2 x + 3
Step-by-step explanation:
So to solve this problem we have to look at the graph.
We have to put it into y = mx + b.
The B would be where the line crosses the y - intercept.
The mx would be how fast is the line going up/down.
If it is going down, it would be negative.
If it is going up, it would be positive.
I hope I helped.
