Question

From a survey involving 2,000 students at a large university, it
was found that 1,300 students had classes on Monday, Wednesday, and
Friday, 1,500 students had classes on Tuesday and Thursday, and 800
students had classes every day. If a student at this university is
selected at random, what is the (empirical) probability that the
student has classes only on Tuesday and Thursday?

please explain

Answer #1

5. A survey conducted at a Midwestern university and involving
1,500 students found that 68% had
taken out a student loan to help pay for the cost of their
college education. A similar study at a
southeastern university in which 2,000 students were surveyed
found that 47% had taken out a student
loan.
a.Develop and interpret a 95% confidence interval estimate for
the difference in the proportions of
students who have loans at these two universities.
b.Using an alpha level...

Fazila attends a university in which each class holds only once
a week. She has to decide between 30 classes that do not overlap
with one another. There are 6 classes to choose from for each day
of the week and the university follows the rule of 5 day working
week spanning from Monday to Friday. Fazila decides to register for
7 randomly selected classes out of the 30, with all choices equally
likely. What is the probability that she...

Fifteen percent of all students at a large university are
absent on Mondays. If a random sample of 12 names is called on a
Monday, what is the probability that four students are absent? (Use
normal approximation to the binomial distribution to answer this
question)
5a)A University found that 20% of the students withdraw
without completing the introductory statistics course. Assume that
20 students registered for the statistics course. Que # 35 ASW

In a large university, statistics show that 75% of students live
in dormitories. Thus, for any student chosen at random, the
university administration estimates a probability of 0.75 that the
student will live in dormitories. A random sample of 5 students is
selected. Answer the following questions.
1.What is the probability that the sample contains exactly 3
students who live in the dormitories?
2.What is the probability that fewer than 2 students live in the
dormitories?
3.What is the expected...

At Winchester University ( a large university) 43% of the
student body belongs to an ethnic minority. Suppose that 25
students are selected at random; that is, each student is
independent of the other students. Let the random variable X count
the number of students out of 25 that belong to an ethnic
minority
A) State the distribution of the random variable given above
B) Compute the probability that at most 7 of the 25 selected
students belong to an...

A random sample of 200 students was drawn from a large
university. It was found that 73 students in this sample live in
off-campus apartment. Construct a 90% confidence interval for the
proportion of students in this university that live in off-campus
apartment. Use normal approximation in this question.
You can also take a look at Wilson score
interval.

A large population of male college students had a nightly
sleep time on Monday through Thursday that is normally distributed
with a mean of 6.1 hours and a standard deviation of 1.9
hours.
a. If one of these students is selected at random, what is the
probability that he has a mean sleep time less than 7 hours?
b. If a sample of 30 of these students is chosen, what is the
probability that their mean sleep time is less...

A random sample of 16 students selected from the student body of
a large university had an average age of 25 years and a standard
deviation of 2 years. We want to determine if the average age of
all the students at the university is less than equal to or greater
than 24. Assume the distribution of the population of ages is
normal. Using α = .05, it can be concluded that the population mean
age is
not different than...

A random sample of 16 students selected from the student body of
a large university had an average age of 25 years and a standard
deviation of 2 years. We want to use hypothesis testing to
determine if the average age of all the students at the university
is significantly more than 24. Assume the distribution of the
population of ages is normal.
The value of the test statistic is
The p-value is between
a. .01 and .02
b. .02...

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. a) How would
the confidence interval change if the confidence level had been
90% instead of 98%? The new confidence interval would be ▼ wider.
narrower....
