Answer 2

Answer:

We will get the mean value is $38.\bar2.$

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

       Given data:- 23,78,42,30,78,44,28,17,4.

       To find:- Value of mean.

       Solution:-

• We know that mean is an arithmetic average of all numbers.

• It is the sum of all numbers divided by the total number of observations.
• The formula of mean is

          $mean =\frac{\text { Sum of all number }}{\text { Total number of observation }}$

           Therefore, we  get

           $\text { mean }=\frac{23+78+42+30+78+44+28+17+4}{9} \\\text { mean }=\frac{344}{9} \\\text { mean }= 38.\bar2$
