The correct answer is option C. The ORDER= option within the PROC EXPORT statement allows you to specify the order of variables in the exported file. It takes a list of variables enclosed in parentheses- The correct syntax is ORDER=(Product_Name Product_lD Price). Option A exports the data without specifying an order- Option B and D specify invalid ORDER= options. Option E specifies the ASCENDING order, which is not what the question asks.

The code creates two datasets, preteen and teen, based on the age variable from the sashelp.class dataset. The if statement checks each observation, and if the age is less than 13, the observation is written to the preteen dataset; otherwise, the observation is written to the teen dataset.
From the provided frequency table, we can see that there are 7 observations with ages less than 13 (2 for age
11 and 5 for age 12), so the preteen dataset will have 7 observations. Since the sashelp.class dataset has a total of 19 observations, the remaining 12 observations (19 total - 7 preteen = 12 teen) will be written to the teen dataset.
Thus, the answer is: B. preteen will have 7 observations and teen will have 12 observations.

The correct option is E. Here's why: PROC EXPORT is used to export SAS datasets to external files. DATA-ORDERS specifies the SAS dataset to be exported. OUTFILE='orders_exportcsv' indicates the location and name of the CSV file to be created. DBMS=CSV specifies the type of data source as a CSV file. REPLACE ensures any existing file with the same name is overwritten. PUTNAMES=YES tells SAS to include variable names in the first row of the CSV file. FORMAT Order_Date=DATE9. Total_Amount=COMMA12.2 applies the desired formatting to the specified columns. DATE9_ formats the 'Order_Date' column as 'YYYY-MM-DD', while COMMA12.2 formats the 'Total_Amount' column as a comma-separated numeric value with 2 decimal places. SORT BY Order_Date sorts the dataset by the 'Order_Date' column in ascending order before exporting it to the CSV file. Why other options are incorrect: Option A: Uses YYMMDDIO. format, which is not the desired format for the 'Order_Date' columm Option B. Doesn't sort the data before exporting. Option C: Uses DOLLAR 12.2 format, which is not appropriate for the 'Total_Amount' column. Option D: Doesnt sort the data before exporting, and uses the OUT-ORDERS clause, which is not required within the SORT statement inside PROC EXPORT

Option D uses the correct syntax for both assigning a label to the 'CUST_ID' variable using the 'label' statement and renaming the 'CITY' variable to 'Location' using the 'rename' statement. The other options either lack the rename statement or use incorrect syntax for applying labels. Option C might seem correct, but it only renames the variable in the print procedure. It does not permanently change the variable name in the dataset.

The correct answer is "A". This code snippet uses the SCAN function to extract the first word from the 'NAME' variable using a space as a delimiter- The LENGTH statement assigns the 'FIRST NAME' variable a length of 20 bytes- Option is incorrect because the LENGTH statement requires an equal sign (z) and not a dollar sign (S) for character variables. Option , is incorrect because the LENGTH statement is applied before the variable is defined, which would result in an error- Option is incorrect because it uses the SUBSTR and INDEX functions to extract the first name, which could lead to errors if the 'NAME' variable does not contain a space or if there is only one word in the name- Option r, E, , is incorrect because it uses the SUBSTR and INDEX functions without specifying the correct starting and ending positions for the first name, which could lead to incorrect results.
