In a random sample of 25 students, 14 students answered "Yes" to the question “Do you use a grocery delivery app?” Use the “plus-four” method to find a 95% confidence interval for the true proportion of students who use a grocery delivery app. Round to 3 decimal places, if necessary.
Homework Answers
Using plus four method we need to 2 in the number of students who answered yes and 4 in the sample size. So we have:
X = 14+2=16 , n = 25+4=29

A simple random sample of 40 students is taken at a community college. Of those, 25 are females. Use the proportion of females in the sample to construct a 95% confidence interval for the proportion of females enrolled on the campus (the population). Round your boundaries to two decimal places (for example(0.25, 0.35)).

Suppose that at a particular college, a random sample found that 25 out of 100 students who use the internet use Twitter. Does this provide evidence that the true proportion of students at this college who use Twitter is higher than the nationally stated 15%?
