Question

The maximum temperature for the first ten days of July, $2006$ in a certain city were:

$43,44,42,41,36,43,42,40$

Calculate mean of the above data.

Answer 1

Finding mean of the given data

Given data, $43,44,42,41,36,43,42,40$

Since, $Mean=\frac{Sumofallobservations}{TotalNumberofObservations}.....\left(i\right)$

Now, total number of observation $=8$ [ From the given data]

sum of all observation $=43+44+42+41+36+43+42+40=331$

So, Mean $=\frac{331}{8}=41.375$ [Using equation (i)]

Hence, mean of the given data is $41.375$.
