Answer 2

Answer:

$for \: group \: data \: we \: use \\ \: the \: given \: formula \: for \: \\ finding \: mode..... \\ mode = l + ( \frac{f1 - fo}{2f1 - fo - f2} ) \times h$

here l is lower limit of modal class

modal class is the class interval of highest frequency..

f1 is the frequency of modal class...

fo is the frequency of preceding modal class..

f2 is the frequency of succeeding modal class..

h is the modal class size..

let's put the values to get the answer..

$mode=150+( \frac{20 - 12}{40 - 12 - 8} ) \times 10 \\ mode = 150 + ( \frac{8}{20}) \times 10 \\ mode = 150 + 4 = 154$

thus, 154 is the mode of given data....

hope this will help u..
