Question

a. The observations of an ungrouped data are a1, a2, and 7a, such that a1
<a2<7a,. If the median and mean of the data are 14 and 18
respectively, find the observations​

Answer 1

Answer:

a1,a2,7a1

now ....

mean of this data is=18

(a1+a2+7a1)/3=18

=>8a1+a2=54

now median is 14

therefore..a2=14

so .....8a1+14=54

=>a1=40/8=5

now....7a1=7(5)=35

the observation are

5,14,35
