The number of building permits issued last month to 12 construction firm in a small Midwestern city were 4,7,0,7,11,4,1,15,3,5,8,and 7. Treating the data as a population, find mean, median and the mode.

Answer 2

Answer:

Step-by-step explanation:

The data is 4,7,0,7,11,4,1,15,3,5,8,and 7

It  is first arranged in the increasing order: $0, 1, 3, 4, 4, 5, 7, 7, 7, 8, 11, 15$

Now, doing the calculations:

Mean = sum of observations/ number of observations

$=$ $\frac{(0+1+ 3+4+ 4+ 5+ 7+ 7+ 7+ 8+ 11+ 15)}{12}$

$=$ $\frac{72}{12}$

= 6

Since here, 12 observations are there, so the median will be 6th and 7th term divided by 2.

Median = $\frac{5+7}{2}$ = 6

7 is the observation occurring the maximum number of times, hence mode is 7.
