In an aarp study of 1019 randomly selected adults, the respondents were asked to identify the number of credit cards they have, and 26% of them said they had no credit cards. is this a statistic or parameter?

The statement is statistic.

Step-by-step explanation:

Consider the provided information.

In an AARP study of 1019 randomly selected adults, the respondents were asked to identify the number of credit cards they have, and 26% of them said they had no credit cards.

A statistic is a feature of a sample, a percentage of the target population. A parameter is set, unknown numerical value, whereas the statistics are a known number and a variable depending on the population part.

Now we have given the percentage of target population which is the descriptive measure for a sample.

26% is the based on the sample of 1019, therefore this a statistic.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3
