A) Taken at a basketball championship, the sample must be considered to be biased—probably in favor of basketball. Any conclusion can only be applied to attendees polled at the championship.
b) If a conclusion is to be drawn about opinions of students at the school, then a method needs to be devised to obtain opinions from a random sample of students. Likely, care would need to be taken to ensure expressed opinions are not influenced by games scheduled or just concluded, or by other factors such as reported injuries. A random sample from a list of student ID numbers might be appropriate. The poll might need to be conducted between seasons.
From greatest to least is 3.9,3.644,3.289,3.099
1) It's probably best to use a credit card instead of using cash for most things. It's safest.
2) I can exchange dollars for British Pounds here in the US, at the airport (In Manchester) or at a British bank? It doesn't really matter when I exchange it since there will be a fee? Is there one better way than another?
3 letters to US = 3*0.94 = 2.82
2 local letters = 2*0.44 = 0.88
checking: 2.82+0.88 = 3.70
to get rid out of 0.04 cents you have to multiply it by 5. so total number of letters would be 5.
May you please provide an image if possible? Thanks :)
