The standard deviation of the numbers is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
We know thatS.D=∑xi-μ2N where, μ→Mean N→Number of terms xi→terms Now, μ=22+26+28+20+24+306 ⇒μ=1506=25 Now, xi xi-μ2 22 22-252=9 26 26-252=1 28 28-252=9 20 20-252=25 24 24-252=1 30 30-252=25 Therefore, ∑xi-μ2=70…
