		Nominal
		Ordinal
		Interval-Ratio
		None of the above.

Question 3

These variable being measured here is at what level of measurement?

		Nominal
		Ordinal
		Interval-Ratio
		All of the above.

Answer 1

Question 1:

Correct option:

Descriptive statistics

Explanation:

Descriptive statistics is a summary statistic that quantitatively summarizes features of a collection of information. Here The firm contacted and interviewed all 125 members of the Kansas Legislature and concluded that 45% favored abolishing the death penalty and 55% opposed abolishing it.

Question 2:

Correct option:

Nominal

Explanation:

The variable of interest is support for abolishing the death penalty in Kansas. So, level of measurement is nominal.

Question 3:

Correct option:

Mode

Explanation:
Mode is the only appropriate for measure of Central Tendency.

Question 4:

Correct option:

Inferential statistics

Explanation:

Inferential statistics allows us to make predictions from that data.Here, the research department drew a random sample of 300 employees and measured their opinions on the health plan. The results showed that 10% were very satisfied, 55% were somewhat satisfied, 35% were somewhat dissatisfied and none were very dissatisfied, with a margin of error of +/- 5.5%.

Question 5:

Correct option:

Ordinal

Explanation:
Here the variable of interest is how satisfied her employees were with the current health plan and so it can be ranked.
