What is the calculated chi-squared value?

Answer #1

(A) We assume that the proportion of green should be same for all three, i.e. p = 1/3

total frequency = 30+80121 = 231

Expected value for West Green = total frequency*proportion = 231*(1/3) = 77

(B) We assume that the proportion of green should be same for all three, i.e. p = 1/3

total frequency = 34+51+80 = 165

Expected value for each Green = total frequency*proportion = 165*(1/3) = 55

32. Suppose a survey is conducted five years ago at a university
showed that there are 500 students out of all the 5000 students
would like to go graduate school after they obtained the bachelor’s
degree. This year a new survey was conducted on a random sample of
500 students from this university, and it was found that 80 of them
would like to go graduate school after they graduate. Do these data
provide convincing evidence to suggest that the...

Q1. In a study of binge drinking among undergraduates at Ohio
University, a researcher was interested in gender differences as
related to binge drinking and to drinking-related arrests. She
wanted to know two things: (a) Is there a significant relationship
between gender and binge drinking (as defined by 5 or more drinks
at one sitting), and (b) Is there a significant relationship
between gender and drinking-related arrests? A random sample of
males and females were asked about their experiences with...
