Statistics HW help... (easier problems i think)

[kaz2107]

n e one good at stats?!?!?! i have about 4 easyish problems i have to turn in that count for my test and really have no idea how to do them. i will pay someone or trade like an hour of coaching for wut would take no more then like 15 mins if u know wut u r doing. let me kno



here r the problems...

the first one i just need number 2.




and for this one i need numbers 5 and higher...







so if n e one can do those CORRECTLY and thinks it is worth an hour of coaching or like 30 or 40 bucks let me kno so i dont fail out of school thanks.
