I cant figure out what test is needed to be used to solve this problem, any help would bee apreaciated

Two polls (each based on a random sample of 1000) released just before the recent Ontario

provincial election seemed to suggest conflicting outcomes.

The breakdown in percentages for the two polls were:

Liberal PC NDP Green

Angus Reid 33% 36% 26% 5%

Ekos 37.7% 31.5% 23.3% 5.9%

(a) Test at the .05 level of significance whether the data constitute evidence of a

real overall disagreement between the two polls.

(b) In particular, test whether the data constitute evidence of a real disagreement

between the levels of support for the PC party between the two polls. Use the

.05 level of significance.
 
Are you trying to say if those results are significantly/statistically different? Don't you need t test and confidence intervals for that? I don't remember too much stats, I needed it for chem last year.
 
yes i beleive a t test is needed, but im not sure how to do it with 4 different parties from the 2 different polls. Im not sure on formula for it
 
sorry bro, t tests and other stats shit for me are in the category of "learn well enough to get an A, then promptly erase from my memory." im sure there are some great help websites and shit for it though, id search google like a mofo
