Question

If ui = xi - 25/10, sigma fiui = 20 and sigma fi = 100, then find the value of x

Answer 1

Thank you for asking this question, here is your answer:

ui = x base i A/ h

ui = x base i - 25/ 10 (this is given)

A = 25

h = 10

x = A + h x sigma (fiui) / sigma(fi)

= 25 + 10 x 20/100

= 25 + 2

= 27

27 is the final answer for this question.

Answer 2

Answer:

Step-by-step explanation:

We know that,ui = xi − Ah ,

where A is the assumed mean and h is the class size.

Now, ui = xi − 2510 (Given)

So, A = 25; h = 10

Now, x = A + h×sigma(fiui)sigma(fi)

=25 + 10 × 20100

=25+2

=27
