when 294 college students are randomly selected and surveyed, it is found that 130 own a car. Find a 90% confidence interval for the proportion of all college students who own a car. Show all work!!
Homework Answers
Given n=294, p = 130/294 = 0.44 and q = 1-p = 0.56
So, mean = np = 130 and standard deviation = sqrt(npq) = sqrt(294*0.44*0.56) = 8.53
Critical value for 90% confidence interval is 1.64

80% of students at a College live on campus. 120 randomly selected students at the college are surveyed and asked their living situation. Let p̂ be the proportion of students in the sample survey who report they live on campus. a) Find the mean and standard deviation of the sampling distribution of p̂. b) Use normalcdf with the sample proportion p̂ to determine the probability that at least 75% of the students in the survey live on campus.
