A professor records the time (in minutes) that it takes 16 students to do a exam. Compute theSS, the variance, and the standard deviation assuming the 16 students constitute a population and assuming the 16 students constitute a sample. (Round your answers for variance and standard deviation to two decimal places.)45494224261540512644333929453430

(a) the 16 students constitute a population

SS= variance= standard deviation=

(b) the 16 students constitute a sample

SS=variance=standard deviation=
