1.	For the given scores \(\overline{X}\) = 12 and Σxi = 192, then n = A) 12 B) 15.8 C) 16 D) 18
Answer» Correct option is (C) 16 \(\overline X=\frac{\sum x_i}n\) \(\Rightarrow\) \(n=\frac{\sum x_i}{\overline X}\) \(=\frac{192}{12}\) = 16 Correct option is C) 16

For the given scores \(\overline{X}\) = 12 and Σxi = 192, then n = A) 12 B) 15.8 C) 16 D) 18

Answer»

Correct option is (C) 16

\(\overline X=\frac{\sum x_i}n\)

\(\Rightarrow\) \(n=\frac{\sum x_i}{\overline X}\)

\(=\frac{192}{12}\) = 16

Correct option is C) 16
