If the standard deviation of 0 ,   1 ,   2 ,   . . . ,   9 is k , then the standard deviation of 10 ,   11 ,   12 ,   . . .   ,   19 is

Options

  1. Ak
  2. Bk + 10
  3. Ck + 1 0
  4. D10 k

Correct answer

A. k

Step-by-step solution

Here, we see that 10 is added in each observation of the first data. Since we know that SD does not depend on change of origin. Hence, SD of second data is k .

Consider a data consisting of 10 observations x₁, x₂, , x₁₀ , whose mean is 5 and variance is 7 . If the mean and the variance of the first 8 observations x₁, x₂, , x₈ are 4 and 3. 2026A set of four observations has mean 1 and variance 13 . Another set of six observations has mean 2 and variance 1 . Then, the variance of all these 10 observations is equal to: 2026Let the mean and the variance of seven observations 2, 4, , 8, , 12, 14 , < , be 8 and 16 respectively. Then the quadratic equation whose roots are 3 + 2 and 2 + 1 is : 2026A data consists of 20 observations x₁, x₂, , x₂₀ . If _ i=1 ²⁰(x_i + 5)^2 = 2500 and _ i=1 ²⁰(x_i - 5)^2 = 100 , then the ratio of mean to standard deviation of this data is: 2026A variable X takes values 0, 0, 2, 6, 12, 20, , n(n-1) with frequencies ^nC₀, ^nC₁, ^nC₂, ^nC₃, ^nC₄, ^nC₅, , ^nC_n , respectively.
