Answer:
Standard deviation = 5.1
Mean = 13
Median = 14
Step-by-step explanation:
The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation
The mean of a set of numbers is the sum divided by the number of terms.
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
<em>I think the best answer is:</em>
Explanation Below.
This is a proper fraction once the absolute value of the top number or numerator (4) is smaller than the absolute value of the bottom number or denomintor (52).
The fraction
can be reduced.
We will use the Greatest Common Factor (GCF) method to simplify it.
The GCF is the largest number between which two or more numbers can be divided evenly.
To find the GCF we list the the numerator and denominator factors (*) then we find the largest number that is repeated in both lists:
* The factors of 4 are 1,2,4;
* The factors of 52 are 1,2,4,13,26,52.
We can see that the GCD is 4 because it is the largest number by which 4 y 52 can be divided without leaving any residue.
To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF).
So,

The factors are numbers that multiply each other to get another number. For example, 2 and 3 are factors of 6, because by multiplying them you get 6.
