Answer #1

3) Given data

First write in ascending order

Sample size (n)=9

4,4,5,6,6,7,10,11,14

a) Mean=sum/number of variables

=(4+4+5+6+6+7+10+11+14)

=67/9 =7.44

b)Mode =number of most repeating Number in the data

=Two modes are there(4 and 6)

c) Range =Highest-Lowest

=14-4 =10

4)we need to determine the which score was better among two subjects
