The better statistics which can be used to compare the given distributions are mean and standard deviation.
<h3>What is a z-core?</h3>
A z-core is also referred to as a standard score and it can be defined as a statistical measure of the distance between a data point (raw score) and the mean, especially when standard deviation units are used.
In Mathematics, z-scores can either be negative or positive and it is generally calculated by using this formula:
<u>Where:</u>
- x is the observed data or sample mean.
- is the standard deviation.
In conclusion, the better statistics which can be used to compare the given distributions are mean and standard deviation.

.83 is the answer 5/6 = .83333333 but rounding its .83
Here’s the answer and how i worked it out step by step. hope this helps :)
Answer:
There are 14 horses and 21 chickens.
Step-by-step explanation:
First, you have to make expression for horse and chicken. So we can let x be the number of horses and y will be the number of chickens. Next, given that the total number of feet for both animals is 98 so you have to make simultaneous equation :
( horse has 4 feet and chicken has 2 feet )
There are a total of 35 heads so the other equation will be :
Lastly, you have to solve it :
Answer:
x = ±4
Step-by-step explanation:
Hi there!
Move 16 to the other side
Take the square root of both sides
I hope this helps!
