Question

What is the average of all the entries in the following table?

Day	Temperature (in degree celsius)
Monday	25
Tuesday	29
Wednesday	32
Thursday	34
Friday	31
Saturday	26

• A.
  34
• B.
  32
• C.
  29.5
• D.
  26.5

Answer 1

The correct option is C

29.5
We know,

Average = $\frac{Sumofallobservations}{Totalnumberofobservations}$

Here,
Sum of all observations = 25 + 29 + 32 + 34 + 31 + 26 = 177
Total number of observations = 6

$\therefore$ Average = $\frac{177}{6}=29.5$
