Mean of 200 items is 48 and their standard deviation is 3. Find the sum of all the items and the sum of the squares of all the items.

Solution:

Mean of 100 items (x̄) = 48

Standard deviation (σ) = 3

here we have to answer for two questions that is sum of all items (Σ x) and sum of squares all items (Σ x²).

x̄ = (Σ x/n)

48 = (Σ x/200)

Σ x = 200 x 48

     = 9600

Sum of all items = 9600

To find sum of squares of all items, we have to find variance (σ²).

σ² = (Σ x²/n) - (Σ x/n)²

(3)² =  (Σ x²/200) - (9600/200)²

(3)² =  (Σ x²/200) - (48)²

9 = (Σ x²/200) - 2304

9 + 2304 = (Σ x²/200)

2313 = Σ x²/200

Σ x² = 2313(200)

Σ x² = 462600

Sum of squares of all items = 462600
