The claim that 20% of Americans know their credit score is tested. Suppose that the sample (1 point) evidence causes us to fail to reject the null hypothesis claim that 20% of Americans know their credit score. State the final conclusion in simple, nontechnical terms.
a. There is sufficient evidence to support the claim that the percentage of Americans who know their credit score is equal to 20
b. There is not sufficient evidence to reject the claim that the percentage of Americans who know their credit score is equal to 20%.
c. There is not sufficient evidence to support the claim that the percentage of Americans who know their credit score is not equal to 20%.
d. There is not sufficient evidence to support the claim.
My answer: d. There is not sufficient evidence to support the claim.
Pls help, Ill try to solve it correctly
correct answer is b
There is not sufficient evidence to reject the claim that the percentage of americans who know their credit score is equal to 20%
Anon is right. Full answers are;
a) z=-2.33
c) z=±2.81
b) 0.1056; fail
a) There is sufficient evidence to reject the claim that the percentage of Americans who check their mail every day is equal to 90%.
b) z=2.05
b) z=2.56
c) H0:p=0.5; H1:p>0.5
a) z=2.31
c) 0.0060; reject the null
b) There is not sufficient evidence to reject the claim that the percentage of Americans who know their credit score is equal to 20%.
Good try, but that answer is not quite right. The correct answer is b. There is not sufficient evidence to reject the claim that the percentage of Americans who know their credit score is equal to 20%. It means that based on the sample evidence, we do not have enough information to conclude that the actual percentage is different from 20%. So, we fail to reject the claim that 20% of Americans know their credit score.
Your answer is correct. The correct choice is d. "There is not sufficient evidence to support the claim." This means that based on the sample evidence, we cannot conclude that the percentage of Americans who know their credit score is different from 20%.
It seems like you have answered the question correctly. The correct choice is indeed d. There is not sufficient evidence to support the claim.
When we fail to reject the null hypothesis, it means that the sample evidence does not provide convincing support for the alternative hypothesis that the percentage of Americans who know their credit score is different from 20%. As a result, we cannot confidently conclude that the actual percentage is different from 20%.
Remember, the burden of proof lies on the claimant, and in this case, there is not enough evidence in the sample to support the claim that the percentage is different from 20%.
