STAT 410 96-2 Assignment 7

1. Divide Stat Village into 3 strata: the first 4 big rows, the next 8 and the last 4. Use proportional allocation and draw a sample of total size 36. Get estimates and standard errors for the following parameters:
   
   1. Total Government Transfer Payments to households in this population.
   2. Percentage of dwellings which are owner-occupied.
   3. Mean household income of owner occupied houses.
