I don't think so. The pvalue represents the chance of the null hypothesis being wrong. I would say that a pvalue of 1 represents a certainty that the null hypothesis is wrong.My Daughter wants to check her answers to this question. She believes it is 0.05

"the null hypothesis is a general statement or default position that there is nothing new happening, like there is no association among groups, or no relationship between two measured phenomena"I don't think so. The pvalue represents the chance of the null hypothesis being wrong. I would say that a pvalue of 1 represents a certainty that the null hypothesis is wrong.
Right. When you do a statistical test it does not prove the proposition which constitutes the "null" hypothesis. It says that, at 0.05 level for example, the chances of the result being wrong are less than 5% or one chance in 20. with p=1 the chances that the "null" is wrong are certain. With a result greater than the confidence level you are looking for you would reject the "null"."the null hypothesis is a general statement or default position that there is nothing new happening, like there is no association among groups, or no relationship between two measured phenomena"
This didn't make any sense to me, your answer clarified it for me.

She had another one, she thinks it's the last answer and from what I have read it seems to me she's correct.Right.

I think it is the last answer. A random boy has a 95% chance of being within the interval. The confidence interval is roughly ±2σ.She had another one, she thinks it's the last answer and from what I have read it seems to me she's correct.
She felt strongly about 1, she missed that one but still got 95/100.Whatever the "null hypothesis" is, the pvalue represents the probability that the result is different from the null hypothesis (e.g., no difference) merely by chance.
So, I vote for p=0.001
From another perspective (as a test taker), the choices are 0.95, 0.50, 1 (significant figures?), 0.05, and 0.001. Now, you know the most gleeful answer is either large or small. On the large scale is the distractor of 1. That can't be right, unless the database is extremely large. On the other hand, a p=0.001 is possible (with a large database).
In reality, I don't think either p value would be obtained, but 1 is virtually impossible to get on any humaninvolving experiment. The question could have been made harder by this sequence: 0.95. 0.50. 0.98, 0.95 and 0.01.
She got that one correct, she chose the last one.I think it is the last answer. A random boy has a 95% chance of being within the interval. The confidence interval is roughly ±2σ.
By the way a shout out to all who have helped. @jpanhalt @Papabravo and others. She has completed stats, now she has 3 more semesters to go to get her Bachelors, she has already received her Cert as a nurse, she's working currently in a hospital Phsyc ward.She felt strongly about 1, she missed that one but still got 95/100.
She got that one correct, she chose the last one.
