What is the mean absolute deviation (MAD) of the data set?
1 answer:
Answer:
Step-by-step explanation:
The formula for MAD is attached in the pic below.
<em>X_i are all the x values</em>
<em>x bar is the mean (sum of all the numbers divided by the number of numbers)</em>
<em>n is the number of numbers</em>
<em />
Basically, <em>we subtract the mean (x bar) from each of the values and take the absolute value of it and SUM all of them. Then we divide by the number of numbers.</em>
<em />
Thus, mean =
Now,
The MAD is

The statement that 8-37 greater than or equal to 29 is false and the correct statement is 8 - 27 is less than 29
<h3>What is an inequality?</h3>An inequality can be defined as a relation which makes an unequal comparison between two numbers or mathematical expressions.
It is used most often to compare two numbers on the number line by their size
The information given be represented as;
Now, let's find the difference from the left side
We have;
From this, we can see that the statement is wrong as - 29 is neither greater than or equal to 29
The correct statement should be; 8 - 27 is less than 29
Thus, the statement that 8-37 greater than or equal to 29 is false and the correct statement is 8 - 27 is less than 29
