Answer 1

Answer:

6.66

Step-by-step explanation:

Total number of pens = 1+2+3+4+5 = 15

Total cost = 5+10+20+30+35 = 100

Arithmetic mean = total cost / total number of pens

= 100/15 = 6.66

Answer 2

here the no of observation is quite confusing

tip to understand

no of pen- 2

cost of pen -35

In this given example

the number of pen is 2 but the observation is counted as1

this is because the number of pen is 2 not the number of observation is 2 so we counted as one
