Question

Following are the goals scored by two hockey team Shivaji 3 4 2 0 3 1 2 0 6 Rana Pratap 4 0 0 4 3 2 3 3 Which team performs better ?

Answer 1

Step 1 : Finding mean of the data of Shivaji team.

Given data of Shivaji team, $3,4,2,0,3,1,2,0,6$

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

Now, total number of observation $=9$ [ From the given data]

sum of all observation $=3+4+2+0+3+1+2+0+6=21$

So, Mean $=\frac{21}{9}=2.33$ [Using equation (i)]

Hence, mean of the Shivaji team is $2.33$.

Step 2 : Finding mean of the data of Rana Pratap team.

Given data of Rana Pratap team, $4,0,0,4,3,2,3,3$

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

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

sum of all observation $=4+0+0+4+3+2+3+3=19$

So, Mean $=\frac{19}{8}=2.37$ [Using equation (i)]

Hence, mean of the Rana Pratap is $2.33$.

Hence, Rana Pratap team scored better.
