We are 95% confident that 63% to 69% of the 1018 American adults surveyed thought licensed drivers should be required to retake their road test once they turn 65. (b) We are 95% confident that 63% to 69% of American adults thought licensed drivers should be required to retake their road test once they turn 65. (c) If we take many random samples of American adults of size 1018 each, and for each sample, calculated the percentage who thought licensed drivers should be required to retake their road test once they turn 65, 95% of those sample percentages will be between 63% and 69%. (d) The margin of error at a 99% confidence level would be higher than 3%

(c) If we take many random samples of American adults of size 1018 each, and for each sample, calculated the percentage who thought licensed drivers should be required to retake their road test once they turn 65, 95% of those sample percentages will be between 63% and 69%.

Step-by-step explanation:

A random sample is a sample that is chosen at random or randomly in-order to avoid unwanted effect on the sample and also in order to avoid bias on the sample in question.

Bias this is a comparison in favor of or against an idea or thing, this usually happens in a way that is closed-minded, or unfair.

A bias is a systematic error.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

hope this !
