Parameter because the value is a numerical measurement describing a characteristic of a sample. b. Statistic because the value is a numerical measurement describing a characteristic of a sample. c. Statistic because the value is a numerical measurement describing a characteristic of a population. d. Parameter because the value is a numerical measurement describing a characteristic of a population.

Answer 1

b. Statistic

Explanation:

b. Statistic because the value is a numerical measurement describing a characteristic of a sample.

Answer 2

Option b

Explanation:

Given that a sample of employees is selected and it is found that 55 % own a vehicle.

Before we answer the questions let us understand the difference between a parameter and a statistic.

Parameters are numbers that summarizes the data of a population. But statistics are numbers that summarizes the data of a sample.

Sample is a subset of population i.e. a small portion of the whole population is sample.

Here 55% is the proportion of the sample of employees. Since this is a number summarizing the data about a sample this is called statistic.

b. Statistic because the value is a numerical measurement describing a characteristic of a sample.
