Question

1. a)state the two primary parameters and statistics4 total we have studied along with the appropriate symbols for each.

b)describe where parameters and statistics come from.

Explanation:

a) Two common primary parameters and statistics in statistics are the population mean (parameter, symbol $\mu$) and sample mean (statistic, symbol $\bar{x}$). Another pair could be population standard - deviation (parameter, symbol $\sigma$) and sample standard - deviation (statistic, symbol $s$).
b) Parameters come from populations. They describe characteristics of an entire population. Statistics come from samples. They are used to estimate population parameters and are calculated from sample data.

Answer:

a) Population mean: $\mu$, Sample mean: $\bar{x}$, Population standard - deviation: $\sigma$, Sample standard - deviation: $s$
b) Parameters come from populations. Statistics come from samples.
