Step-by-step explanation:

Concept= Mean

Given= Data

To find= Mean of Data

Explanation=

We have been given to find the mean of 9,7,11,13,2,4,5,5.

The ascending order of the data is,

2,4,5,5,7,9,11,13.

Means is the sum of all values and then divided by the number  of observation of the data.

Mean is just like the average value of data.

Mean= Sum of all values/Number of observation

Sum of the given data = 2+4+5+5+7+9+11+13 = 56

Total count of observation of the data given is 8.

Mean= Sum of all values/Number of observation

Mean= 56/8 = 7.

The mean of the data is 7.
