Question

*Researchers, hoping to determine the proportion of Florida
college students who regularly skip breakfast, took a random sample
of 10 Florida colleges. Every student from the chosen colleges was
asked whether or not they regularly skip breakfast.*

**Identify the following:**

- The population of interest
- The population parameter of interest
- The sampling method

Answer #1

Population of interest :

The students of florida college who do take breakfast regularly or not.

Population parameter of interest :

Population parameter of interest is the proportion of students of florida college who regularly skip breakfast.

The sampling method :

The sampling method used here is simple random sample without replacement (SRSWOR)

as we do not wish to consider the same student to come more than once in our sample for our research and any student from the florida college can be selected.

In an effort to determine the percentage of Gainesville
kindergarten students who go door-to-door to “trick or treat” for
Halloween, researchers took a random sample of 10 kindergarten
classes from a list of all kindergarten classes in Gainesville.
Every student from the chosen classes was asked whether or not they
went door-to-door for Halloween.
Identify the following:
1. The population
2. The population parameter of interest
3. The sample
4. The sampling method

Suppose a random sample of 50 college students is asked if they
regularly eat breakfast. A 95% confidence interval for the
proportion of all students that regularly eat breakfast is found to
be 0.69 to 0.91. If a 90% confidence interval was calculated
instead, how would it differ from the 95% confidence interval?
The 90% confidence interval would be wider.
The 90% confidence interval would be narrower.
The 90% confidence interval would have the same width as the 95%
confidence...

Researchers are trying to estimate the mean student loan amount
owed by students in a large university and the proportion of all
students who carry a student loan. A group of 50 students is
randomly selected from each of the 200 majors within the
university. The responses of these students showed that 30% held a
student loan and the mean debt was $18450.

The business college computing center wants to determine the
proportion of business students who have laptop computers. If the
proportion exceeds 30%, then the lab will scale back a proposed
enlargement of its facilities. Suppose 250 business students were
randomly sampled and 75 have laptops. Test if the proportion
exceeds 30%. Use ?=0.05( p value Method) PLEASE DRAW A GRAPH

Throughout the country, the proportion of first-time, first-year
community college students who return for their second year of
studies is p = 0.52 according to the Community College Survey of
Student Engagement. Suppose a community college institutes new
policies geared toward increasing student retention. The first year
this policy was in place there were n = 2843 first-time, first-year
students (N = 1, 050,000). Of these students, x = 1516 returned for
their second year of studies. Treat these students...

Two hundred students were selected at random from those enrolled
at a large college in Alabama. Each student in the sample was asked
whether they ate 5 or more apples in a typical week, and their
cholesterol levels were also measured. The average cholesterol
level was significantly lower for the group who ate 5 or more
apples per week than for the group that did not.
A. Did the study use a random selection from some population? If
yes, what...

The Business College Computing Center wants to determine the
proportion of business students who have laptop computers. If the

is conducted and the test statistic is 2.8. Find the p-value for
a one-sided test of hypothesis.
A. .0026
B..0013

In a study, the researchers were interested in seeing whether if
Ariana Grande’s music can be sexually stimulating to men. The
researchers decided to include male students from Hunter College,
age ranging from 18-20, without pre-diagnosed sexual dysfunctions.
Out of the possible N=10,538 students who meet the criteria for
participation, 200 men were randomly selected by computer to
participate. After having the participants sign the informed
