find the arithmetic mean, mode and range of the data.
rii nfn nortnin locality for a month are given below:​

Answer 1

Answer:

Range 19  Mean 20.2  Mode 21

Step-by-step explanation:

range is the highest - lowest value

                      29       -      10

                  =   19      

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

there are 30 observations

so mean = adding total number of observation/30

=22+17+ 13+ 26+ 29+ 11+ 22+15+ 24+21+ 24+23+21+ 27+ 29+25+15+ 18+ 27+ 19+ 14+ 21+ 15+ 29+ 20+ 12+ 21+ 10+ 16+ 20/30

=20.2

mode is the most frequent value in a data

here it is =

                 21
