Asurvey of 100 random full-time students at a large university showed the mean number of semester units that students were enrolled in was 12 with a standard deviation of 1.9 units. are these numbers statistics or parameters? explain.

Step-by-step explanation:

Given that a survey of 100 random full-time students at a large university showed the mean number of semester units that students were enrolled in was 12 with a standard deviation of 1.9 units.

Recall the difference between statistics and parameters

Parameters are numbers that summarize data for an entire population. Statistics are numbers that summarize data from a sample, i.e. some subset of the entire population

Hence here this is sample taken so the numbers 12 and 1.9 are statistics.
