Question

 In given formula \(\overline { x }\) = a+h\(\left( \frac { { \Sigma f }_{ i }{ u }_{ i } }{ { \Sigma f }_{ i } } \right)\), value of u_i will be : 

(A) h(x_i – a)

(B) \(\frac { { x }_{ i }-a }{ h }\)

(C) \(\frac { { a-x }_{ i } }{ h }\)

(D) \(\frac { { x }_{ i }+a }{ h }\)

Answer 1

Answer is (B) \(\frac { { x }_{ i }-a }{ h }\)
