6. Imagine that I wanted to test the proposition that people think older politicians are more trustworthy. I recruited an internet sample of 90 people. Each person was asked to read a short article about a hypothetical political candidate. Random assignment determined whether the subjects were told that candidate was 65 or whether they were told that candidate was 35. After reading the article, all subjects used a 10-point scale to rate the candidate on competence, trustworthiness, and likability.   I take the mean values of trustworthiness in each group, perform a difference of means test, and find a test statistic of 1.04. Should I reject the null at the 99% confidence level? Why or why not? What does that mean?
I need help with questions 6 through 10. I do not understand how to read the graph based on the questions asked.
