Answer:

hyy mate!!!!

what's up????

Answer 2

Answer:

first, we are finding the median of the factors of 84,

find the factors of 84 which are:

1, 2, 3, 4, 6 , 7, 12, 14, 21,28,42 and 84

now, the number of observations = 12

=1/2 [ ( n/2 )th obs + (n+1/2)th obs ]

=1/2 [ ( 12/2 )th obs + (12+1/2)th obs ]

=1/2 [ 6th obs + 7th obs ]

=1/2 [ 7 + 12]

=1/2 [19]

=9.5

Now we are going to find the mean,

formula for mean is,

sum of observations/nNNo. of observations:

=1 +2+3+4+6+7+12+14+21+28+42+84/12

=224/12

=18.66

median= 9.5

mean=18.66
