2. This question also uses the SAS data file statisticians_orig.sas/bdat (this is already a SAS data file). For each of parts a through I, write SAS statements to create a new SAS data set called statisticians and adding the following variables using the specified variable names. E sure to precede each part of the data step with a comment giving the part name e.g., 5d, and a brief description of the task. a. The first name of the statistician. Call it first with a length of 25. b. The last name of the statistician (the last word in the name) Call it last with a length of 25. Note that some the statisticians have two names, some three and son four. This should be the second if there are two, the third if there are three and the fourth if there are four, etc
