Given:
the lengths of several engineering conferences were announced
Four conferences lasted 8 days,
three lasted 5 days,
ten lasted 9 days,
twelve lasted 7 days,
and three lasted 6 days.
We will find the mean length of the engineering conference
The total number of days =
[tex]8\times4+5\times3+9\times10+7\times12+6\times3=239[/tex]The number of data =
[tex]4+3+10+12+3=32[/tex]so, the mean length = 239/32 = 7.46875
Rounding to the nearest tenth
So, Mean = 7.5 days
B) We will find the median of the data:
We will arrange the data in order from the least to the greatest
three lasted 5 days
three lasted 6 days
twelve lasted 7 days
four lasted 8 days
ten lasted 9 days
As the number of days = 32
so, We will divide the data into 2 equal sections
Each section has 16 data
The data number 16 = 7
The data number 17 = 7
so, Median = 7 days
