A survey asked university students who wanted to go to an exchange program, which city they will choose – London, Paris or Madrid. The exchange programs are only offered in the first and second year. The results are given below in the table.

a) Fill the table. What is the probability that a student chosen at random is a junior and did not select Madrid?
b) What is the probability that a student chosen at random selected London, given that the student is a senior (2nd year)?
c) It seems that Madrid becomes much more popular with second year students than in the first year. Can you figure out if being a second year student and choosing Madrid are independent events? Explain.

A survey of 200 students is selected randomly on a large
university campus They are asked if they use a laptop in class to
take notes. The result of the survey is that 70 of the 200 students
use laptops to take notes in class.
What is the value of the sample proportion? (0.5
pts)
What is the standard error of the sampling proportion?

A survey of 150 students is selected randomly on a large
university campus. They are asked if they use a laptop in class to
take notes. The result of the survey is that 60 of the 150 students
responded "yes." An approximate 98% confidence interval is
(0.307, 0.493). Complete parts a through d below. b) How would
the confidence interval change if the sample size had been 375
instead of 150? (Assume the same sample proportion.) The new
confidence interval...

A survey of 250 students is selected randomly on a large
university campus. They are asked if they use a laptop in class to
take notes. The result of the survey is that 115 of the 250
students responded "yes." An approximate 95% confidence interval
is (0.397,0.523). Which of the following are true? If they are
not true, briefly explain why not

Students enrolled in an introductory statistics course at a
university were asked to take a survey that indicated whether the
student’s learning style was more visual or verbal. Each student
received a numerical score ranging from -11 to +11. Negative scores
indicated a visual learner, and positive scores indicated a verbal
learner. The closer the score was to -11 or +11, the stronger the
student’s inclination toward that learning style. A score of 0
would indicate neutrality between visual or...

A counselor at Cypress College wanted to see if students who are
in the EOPS program at Cypress College have more consistent grades
than students who are not in the EOPS program. To test this, the
counselor obtains random sample of students who are part of the
EOPS program and a sample of students who are not and records their
GPAs. The data is given below. Test the claim that students who are
in the EOPS program have more consistent...

A survey consisting of a sample of 463 first-year college
students at a certain university asked, “About how many hours do
you study during a typical week?” The mean response from the sample
of students was 15.3 hours. Suppose we know that study times follow
a Normal distribution with a standard deviation of 8.5 hours for
all first-year students. Construct a 99% confidence interval for
the mean study time of all first-year college students.

2. The Dean of Students at the University of Waterloo wanted to
estimate the proportion of students who are willing to report
cheating by fellow students. So, her staff surveyed the 172
students currently enrolled in the introduction to biology class.
The students were asked, “Imagine that you witness two students
cheating on a quiz. Would you tell the professor?” 19 of the
surveyed students responded “yes.” (11 points total)
a. Using these data, calculate the 90% confidence interval for...
