A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.20. In a sample of 200 graduates, 30 students have a GPA of 3.00 or below. In testing the university’s belief, how does one define the population parameter of interest?

A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.20. In a sample of 200 graduates, 30 students have a GPA of 3.00 or below
In testing the university’s belief, how does one define the population parameter of interest
Population parameter of interest :
It’s the proportion of honors graduates with a GPA of 3.00 or below.
----------------------------------------------------
As university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.20
i.e
Population parameter : p : proportion of graduates with a GPA of 3.00 or below
In testing the university’s belief, i.e to test p : (proportion of graduates with a GPA of 3.00 or below )< 2 ; Therefore,
the population parameter of interest would be defined as proportion of honors graduates with a GPA of 3.00 or below

We are interested in estimating the proportion of graduates at a
mid-sized university who found a job within one year of completing
their undergraduate degree. We can do so by creating a 95%
confidence interval for the true proportion p. Suppose we conduct a
survey and find out that 340 of the 430 randomly sampled graduates
found jobs within one year. Assume that the size of the population
of graduates at this university is large enough so that all our...

4. The university is interested in determining if the proportion
of graduates obtaining a first-class degree has changed from 2016
to 2017. Out of 2800 graduates in 2016, 560 obtained a first class
degree. In 2017, 805 graduates out of 3500 obtained a first class
degree.
(a) Write down the method of moments estimates for the
proportion of first-class degrees
in 2016 and 2017, pˆ2016 and pˆ2017.
(b) Write down appropriate null and alternative hypotheses for
this test.

A university dean is interested in determining the proportion of
students who receive some sort of financial aid. Rather than
examine the records for all students, the dean randomly selects 225
students and finds that 45 of them are receiving financial aid.
Using a 95% confidence interval, what is the upper limit of the
confidence interval to estimate the true proportion of students who
receive financial aid.

1. We are interested in estimating the proportion of students at
a university who smoke. Out of a random sample of 200 students from
this university, 40 students smoke.
(1) Calculate a 95% confidence interval for the proportion of
students at this university who smoke and interpret this interval
in context.
(2) If we wanted the margin of error to be no larger than 2% at
a 95% confidence level for the proportion of students who smoke,

Suppose that the probability that any random student graduates
with honors is 0.05. Also, we know that the probability of a
student that graduated with honors, getting into graduate school is
0.80. The probability that a student that did not graduate with
honors gets into graduate school is 0.10. TRUE or FALSE: Given that
a random student got into graduate school, it is more likely that
the student graduated with honors.
True
False

with honors is 0.07. Also, we know that the probability of a
student getting into grad school, given that they graduated with
honors is 0.70. The probability of a student getting into grad
school, given that they did not graduate with honors is 0.05. What
is the probability that a student did not graduate with honors,
given that the student did get in to graduate school?
