2. Write SAS statement(s) for each of the following tasks: (a) Set X1 to be the number of days in YEAR, a numeric variable for year, e.g. If YEAR 2000, X1 = 366. = (b) X2 is a character variable for name. It contains two to three words, with the first word being the last name. Define NAME to be the name with the given name presented by the initials, e.g. if x2 = 'Chan Tai Man', then NAME = 'Chan T. M.' and if x2 = 'Chan Keung', then NAME = Chan K.'. ' (c) Set X3 to be the larger root of ax + bx + c = 0 if the polynomial has real roots, and set X3 to a missing value otherwise. (d) Consider AABC with ACB = 52. Denote the length of BC by a, the length of AC by b, and the length of AB by c. Find c given the values of a and b. (e) X4 is a character variable of length 1. Replace the last non-blank character of Y by X4; set Y = X4 if Y = "". 2.
