Q.1 (B)(iv) Find Mean (X) if Σ x_i f_i = 1265 and Σ f_i = 50 .

Answer: X = 25.3 X = Σ x_i f_i/Σ f_i = 1265/50 = 25.3 .

Find Mean \((\bar{X})\) if \(\sum x_i f_i = 1265\) and \(\sum f_i = 50\).

Best answer

Answer: \(\bar{X} = 25.3\)

\(\bar{X} = \dfrac{\sum x_i f_i}{\sum f_i} = \dfrac{1265}{50} = 25.3\).
