Hello, I am doing a research project for statistics and I have 2 questions I am having trouble with. my Sample size (n=34) using a two sample t-test for this following study:

"There were 34 participants recruited for this study from a college campus and randomly divided into 2 groups. Both groups were shown a 58-second video of a crime scene scenario in which the suspect's facial characteristics were clearly visible at two separate points and occasionally visible at other times throughout the video. The 17 participants in Group A were shown a 5-individual lineup that contained the suspect in the video. The 17 participants in Group B were shown a 5-individual lineup that did not contain the suspect. All participants were asked to identify if and where the suspect was in the lineup and provide a rating of confidence on a scale from 1 to 10 that the selection was the same person as seen in the video committing the crime. Since this study would be an experiment, Group B would be the control group and Group A would be the experimental group because Group A was exposed to the actual suspect and the participants in Group B were not. The question that can be answered by the data, "Is there is a difference in confidence between group A, which was set up to be right and group B, which was set up to be wrong?"

The questions I am having trouble answering are:

1. Indicate your research hypotheses (null and alternative), incorporating the appropriate symbols. [To answer this question, you need, in part, to look at the research scenario.]
2. State what the hypotheses mean. [Some overlap may exist with your answer to # 1. These are related rather than mutually exclusive questions.]
