Answer 1

Answer:

B.

Step-by-step explanation:

A parameter is a summary measure computed to describe a characteristic of the population  and it involves the measurement  of all in the population numerically/quantitatively. e.g  Average of all the values measured in the population

A statistic is a measurement based on sample observations.

Examples of statistics constructed from a random sample : [ $X_{1}.....X_{n}$

(a) max$(x_{1}....x_){n}$

(b) Average of the observed values

(c) Range  = max - min
