Question

a simple random sample of 5000 students were selected
and asked how likely to for them to maintain a 6 feet distamce in
the classrooms if they return to campus. among the sample 5000 ,
76% of the students responded that they are somewhat or very likely
to keep the physical distance in classrooms

1. University is intrested in releasing an interval estimate for
the true proportion of students who would be (somewhat or very
likely to keep their physical distance). What are the conditions
that need to be satisfied in order for us to calculate the
confidence interval. Are they satisfied?

2.) Calculate the 90% Confidence interval for the proportion (of students somewhat or very likely to keep their physical distance)?

3.)Interpret the interval calculated in part 2?

4.) Based on the interval you calculated in part 2 we can say more than 70% of penn state students would (somewhat or very likely to keep their physical distance). Explain your anwser?

In a simple random sample of 500 freshman students, 276 of them
live on campus. You want to claim that majority of college freshman
students in US live on campus.
A) Are the assumptions for making a 95% confidence interval for
the true proportion of all college freshman students in the United
States who live on campus satisfied? yes/no?
B) What is the sample proportion?
C.) A 95% confidence interval for the actual proportion of
college freshman students in the...

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. Suppose that based on the survey, 120 of the 200
students responded "yes." a) What is the value of the sample
proportion ModifyingAbove p with caret? b) What is the standard
error of the sample proportion? c) Construct an approximate 95%
confidence interval for the true proportion p by taking plus or
minus 2...

In a random sample of 35 Penn State Shenango students, 17 were
attending full-time. In a random sample of 40 World Campus
students, 13 were attending full-time.
Use Minitab Express to construct a 95% confidence interval to
estimate the difference between the proportions of all Penn State
Shenango and all Penn State World Campus students who are attending
full-time. If assumptions are met, use the normal approximation
method. Remember to copy + paste all relevant Minitab Express
output. Clearly identify...

(a). A simple random sample of 37 days was selected. For these
37 days, Parsnip was fed seeds on 22 days and Parsnip was fed
pellets on the other 15 days. The goal is to calculate a 99%
confidence interval for the proportion of all days in which Parsnip
was fed seeds, and to do so there are two assumptions. The first is
that there is a simple random sample, which is satisfied. What is
the second assumption, and specific...

A survey of 180 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 90 of the 180 students
responded "yes". An approximate 98% confidence interval is (0.413,
0.587). Complete parts a through C. a) How would the confidence
interval change if the confidence level has been 95% instead of 98%
b) How would confidence interval change if the sample size...

7. A survey of 300 students is selected randomly on a large
university campus. They are asked if they use a laptop in class to
take notes. Suppose that based on the survey, 120 of the 300
students responded "yes."
a) What is the value of the sample proportion p (with the ^ on
top of p)?
b) What is the standard error of the sample proportion?
c) c) Construct an approximate 95% confidence interval for the
true proportion p...

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?
What is the standard error of the sampling
proportion?
Construct an approximate 95% confidence interval for the true
proportion by going 2 standard errors from the sampling...

Each person in a random sample of 5000 "likely voters" was
questioned about his or her political views. Of those surveyed,
3402 felt that "the economy's state" was the most urgent national
concern.
A. Using the plus four estimate, p, we estimate the proportion
of likely voters that felt the economy's state was the most urgent
national concern to be:
B. The standard error SE of p, the estimated proportion viewing
the economy's state as most urgent, is:
C. A...
