Question

The Standard Deviation of 3, 7, 2, 9, 8, 4, 10, 1, 6, 11, 5 is ?​

Answer 1

Answer:

KEAM 2011: If the standard deviation of 3, 8, 6, 10, 12, 9, 11, 10, 12, 7 is 2.71, then ... 4. The differential equation representing the family of curves y2=2c(x+3√ c), where c is a ... 5. The solution of the differential equation xdydx+y=1x2 at (1,2) is.

Answer 2

Step-by-step explanation:

Given observation is, 3,7,2,9,8,4,10,1,6,11,5

Here n=11 ∑xi= 66, ∑xi^2= 506

∴ Required standard deviation is σ=

√[ ∑xi^2 - (∑xi)^2] = √10

[n ( n)^2]
