The following SAS program inputs information about hospitals in cities in different states, such as the size of the state and the cities (i.e., population), median income and median housing costs, the number of admissions, and the number of beds, using three different data types 1, 2, and 3. Answer the questions below:

data hospital;

retain Form_Id State Stpop CitySize Income Housing Admit Beds;

input Form_Id $3. @5 Type $1. @ ;

if Type =‘1’ then input @8 State $2. Stpop 10.;

if Type =‘2’ then do;

input @8 CityPop 8. Income 5. Housing 6.;

if CityPop<60000 then CitySize=’Small’;

else CitySize=’Large’;

end;

if Type =‘3’ then do;

input @8 Admit 6. Beds 4.;

output;

end;

drop Type CityPop;

a. Show the contents of the PDV immediately after processing the first line of data.

b. Show the contents of the PDV immediately after processing the second line of data.

c. Show the contents of the PDV immediately after processing the third line of data.

d. Show the contents of the PDV immediately after processing the fifth line of data (before the observation is output to the SAS data set).

e. Display the first observation written to the SAS data set.

f. Run this program and turn-in the output only.

g. Examine the output produced by the second proc print step. Describe the statistics printed in each line of this output, i.e., explain what the computed numbers are in each line. Make sure that, for each value of the TYPE variable, you identify the group of observations used to compute the statistics that appear in that line.
