What is Modal class?
Modal class is the class containing the mode .
What is mode ?
Mode is the highest appearing frequency.
SOLUTION
( M ) Mode = ?
( L ) Lower limit of modal class = 80
( f2 ) frequency of preceding class = 71
( f1 ) frequency of previous class = 42
( h ) class interval = 20
M = L + ( fm - f1 ) h / ( 2 fm - f1 - f2 )
= 80 + ( 82 - 42 ) 20 / ( 164 - 42 - 71 )
= 80 + 40 . 20 / 51
= 80 + 800/51
= 80 + 15.686
= 95.686
= 95.69
Mode = 95,69
ANSWER
95.69 hours
