Question

the standard deviation of first 25. natural numbers​

Answer 1

Answer:

the correct answer is:

2√(13)

Explanation:

we know that the Standard Deviation of first n natural numbers is ;

s.d = √[(n^2 - 1)/12]

for first 25 natural numbers..put n=25;we get,

s.d = √{(625-1)/12}

= √{624/12} = √(52) = 2√(13)
