Question

A student organization wondered how many hours per week college students study during a term. The organization obtained a list of all students at their university and randomly selected 100 from the list. They contacted all 100 students and all 100 provided their best estimate of the number of hours they typically study per week. A 95% confidence interval for the mean number of hours studied per week was constructed. Based on this study, to what population can we make an inference using the confidence interval?

Answer #1

Given that the student organization want to estimate mean number of hours per week college student study during exam. They find the 95% confidence interval for the mean number of hours per week college student study during exam from a random sample of 100 obtained from their University.

Therefore the population for which we make inference using the confidence interval is the number of hours week college student study in the give University.

Since random samples are selected from this university.

In order to determine how many hours per week freshmen college
students watch television, a random sample of 25 students was
selected. It was determined that the students in the sample spent
an average of 19.5 hours with a sample standard deviation of 3.9
hours watching TV per week. Please answer the following questions:
(a) Provide a 95% confidence interval estimate for the average
number of hours that all college freshmen spend watching TV per
week. (b) Assume that a...

A professor wants to estimate how many hours per week students
study. A simple random sample of 78 students had a mean of 15.0
hours of studying per week. Construct and interpret a 90%
confidence interval for the mean number of hours a student studies
per week. Assume the population standard deviation is known to be
2.3 hours per week

The mean number of hours of study time per week for a sample of
554 students is 22. If the margin of error for the population mean
with a 95% confidence interval is 2.1, construct a 95% confidence
interval for the mean number of hours of study time per week for
all students.

A class survey in a large class for first-year college students
asked, "About how many hours do you study during a typical week?"
There were 464 responses to the class survey. Suppose that we know
that the study time follows a Normal distribution with standard
deviation
σ = 8.6
hours in the population of all first-year students at this
university.
One student claimed to study 10,000 hours per week (10,000 is more
than the number of hours in a year)....

Sixty college students were surveyed about the number of hours
they watch television per week. The sample mean was 6.405 hours
with a standard deviation of 5.854. Construct a 99% confidence
interval for the mean number of hours of television watched by all
college student.
Find the value of z or t, whichever is appropriate. Be sure to
draw a bell curve
illustrating
the confidence level.
b)
Find the value of the standard error (SE).
c)
Find the value of...

Dean Halverson recently read that full-time college students
study 20 hours each week. She decides to do a study at her
university to see if there is evidence that students study an
average of less than 20 hours each week. A random sample of 34
students were asked to keep a diary of their activities over a
period of several weeks. It was found that he average number of
hours that the 34 students studied each week was 17.9 hours....

The college is interested in determining how many hours each
week students spend working each week. They wish to estimate the
number to within half an hour. A small pilot study showed a mean
number of hours worked of 33 with a standard deviation of 4.8
hours. How many college students should the college study if they
wish to be 99% confident of their results?
