Homework Answers
- In this question, we are to test if the actual proportion of
grad students living on campus is less than 0.3 or not. Hence, it
is observed that only one parameter is involved. Hence, the test is
for a single proportion.
Hence, the correct option is
D) Test for a Single Proportion .
- Here, we are to test which city has lower mean of the house
rents of one bedroom and one bathroom properties in a month, Hence,
the data is of two samples - one from Chandler and the other from
Gilbert AZ. However, the room rents of Gilbert AZ is independent of
Chandler and vice versa. Hence, here the test is of independent two
sample means.
Hence, the correct option is:
B) Test for Difference in Means .
- Here, we are to test if there exists any relationship between
the course is a required course or an elective course and the
rating of the course. Hence, here, we test for association of the
two variables. Hence, the correct option is:
G) Test for Association (Independence) .

11. As the November temperatures begin to cool off a bit in Arizona, hiking becomes a popular outdoor sport attracting people of all ages. One of the most populat hiking areas in Phoenix is Camelback Mountain. Two Arizona State University researchers want to know if there is an association between the time (in minutes) it takes to hike Camelback Mountain and the age of the hiker (in years.)

A study is conducted to determine what percentage of students live on campus at a large university. In a random sample found of 50 male students, it was found that that 27 of them lived on campus. In a sample of 55 female students, it was found that 40 lived on campus. At the .05 level of significance, does this sample data provide sufficient evidence to conclude that a difference exists between the proportion of male students who live on...
