Answer 1

Answer:

hey your answer is as follows

so pls mark it as brainliest

Step-by-step explanation:

a.so here among the given numbers ie ages of 1 students

smallest value=5

largest value=18

so Range=Largest Value-Smallest value

=18-5

=13

thus our required range is 13

b.moreover mean of above data=

sum of all values/total values

=12+15+14+7+10+16+18+5+9+11+17+8/12

=142/12

=11.8333

=11.834

thus mean of above data is 11.834
