A random sample of 337 college students was asked whether or not they were registered to vote. We wonder if there is an association between a student's sex and whether the student is registered to vote. The data are provided in the tables below (expected counts are in parantheses) (All the conditions are satisfied-don't worry about checking them).
Write appropriate hypotheses:
(a) Mean of the registered Men equals the mean of the registered registered women.
Mean of the registered Men differs from the mean of the registered women.
(b) student's sex is independent of whether the student is registered to vote.
student's sex is not independent of whether the student is registered to vote.
(c) There is no linear correlation between sex and whether a student is registered to vote
There is linear correlation between sex and whether a student is registered to vote
(d) Let d= Registerd-Note Registered
The mean difference in registered is zero.
The mean difference in registered is less than zero.
(e)
