Answer:
C.
Mean= 4.9
Mean Absolute Deviation (MAD): 4.099173553719
Step-by-step explanation:
An outlier is a value that is very different from the other data in your data set. This can skew your results. As you can see, having outliers often has a significant effect on your mean and standard deviation. Because of this, we must take steps to remove outliers from our data sets.

Answer:
Option A is correct.
Value of
Step-by-step explanation:
Given: and common difference(d) = 3.4
A sequence of numbers is arithmetic i.e, it increases or decreases by a constant amount each term.
The sum of the nth term of a arithmetic sequence is given by;
, where n is the number of terms, a is the first term and d is the common difference.
We also know the nth tern sequence formula which is given by ;
......[2]
First find a.
it is given that
Put n =12 and d=3.4 in equation [2] we have;
2.4 = a + 37.4
Simplify:
a = - 35
Now, to calculate
we use equation [1];
here, n =2 , a =-35 and d=3.4
Simplify:
Therefore, the sum of sequence of 22nd term i.e,
