In calculating the mean of this data set Ashrita did the best job.
The Mean of the data set is the most commonly used measures of central tendency.
It means the average value of the data set.
one doesn't have to arrange the data in order for finding it.
<h3>What is the meaning of mean?</h3>
The data set value takes is to add them all together and divide that by the number of the data.
It can be written as
Where 
are the values in the data set
Therefore we can conclude that Ashrita did the best job in calculating the mean of this data set.

Answer:
Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.
Step-by-step explanation:
Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.
z-score:
- A z-score is a numerical measurement which is measured in terms of standard deviations from the mean.
- Formula:
- If a z-score is 0, it tells that the data point is same as the mean.
- Area under the normal curve is 1.

Mathematically speaking, the statement is equivalent to this 2-variable non-linear system:
First, 
is cleared in the first equation:
Now, the variable is substituted in the second one:
And some algebra is done in order to simplify the expression:
Roots are found by means of the General Equation for Second-Order Polynomials:
and 
There are two different values for :
There are two possibilities:

ANSWER
"If x=7, then x - 2 = 5"
EXPLANATION
Let
be a propositional statement.
The converse of this statement is
In other words, the converse of the statement,
"If p then q" is "If q, then p"
The given given conditional statement is
"If x - 2 = 5, then x = 7"
Therefore the converse is
"If x=7, then x - 2 = 5"
