Explanation of Solution
Parameter refers to any statistical measure that is based on all units in the population.
(d)
To determine
Define statistic.
(d)
Expert Solution
Explanation of Solution
Any statistical measure calculated on the basis of sample observation is called statistic.
(e)
To determine
Define statistical inference.
(e)
Expert Solution
Explanation of Solution
If the data consist of different methods for estimating the sample and drawing the inferences about the features of the population, then it is termed as a statistical inference.
