You refer to a rectangular distribution. 

I.e. Area ∝ probability 

so, length x height = area 

=> 6 x height = 1 

so, height = 1/6 

Therefore, greater than 2.25 minutes => 8-2.25 = 5.75 minutes 

=> 5.75 x 1/6 = 0.9583

 

Since this is uniformly distributed, there is no need to find the height or standard deviation.

Answer:

Neighborhood Q appears to have a bigger family size

Step-by-step explanation:

Mean = the sum of all data values divided by the total number of data values

Number of families in Neighborhood Q = 9

Mean family size of Neighborhood Q:

= (2 + 5 + 4 + 3 + 2 + 5 + 3 + 6 + 5) ÷ 9

= 35 ÷ 9

= 3.888888...

Number of families in Neighborhood S = 9

Mean family size of Neighborhood S:

= (2 + 3 + 2 + 3 + 7 + 2 + 3 + 3 + 2) ÷ 9

= 27 ÷ 9

= 3

The mean family size of Neighborhood Q is 3.88..  and the mean family size of Neighborhood S is 3.  Therefore, Neighborhood Q appears to have a bigger family size as it's average family size is bigger than that of Neighborhood S.
