<PRE><B>Question 883167</B>
The table below shows the numbers of two- to five-bedroom houses in the Belmont neighborhood.
 Number of Bedrooms Frequency
 2 12
 3 40
 4 70
 5 3
 What is the mean number of bedrooms in a house in this neighborhood?
---
# of bedrooms = 12*2 + 40*3 + 70*4 + 3*5 = 24+120+280+15 = 439
# of houses = 12+40+70+3 = 125
--
Mean Number of bedrooms = 439/125 = 3.51
