Help with math?

PLEASE SHOW ALL WORK AND EXPLAIN YOUR ANSWERS One question is the picture (Friday) and this is the other one: In a town with a population of 85,000, 35 percent of the voters are registered as independent. In a sample of 1,000 voters randomly chosen for a survey, 25 percent were registered as independent. Which statement best describes why the sample was NOT valid? A. The sample was chosen at random B. The sample included many more people than necessary. C. The sample did not include all the voters in the city. D. The sample was not representative of the voters registered as independent.
Well, on average player B does get a higher number of home runs, as the box plot shows. Also Player B is more consistent as his 50% middle box (can't remember what it's called) is smaller, showing that he normally had a smaller range of data. And I'm too lazy to do the other one :)
