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 200 students and finds that 118 of them are receiving financial aid. If the dean wanted to estimate the proportion of all students receiving financial aid to within 3% with 98% reliability, how many students would need to be sampled?

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 135 of them are receiving financial aid. Use a 90% confidence interval to estimate the true proportion of students who receive financial aid.

A dean at a large state university (student population exceeds 40,000) 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 200 students and finds that 118 of them are receiving financial aid. When the dean repeated this study the next year, she used a sample of 256 students and obtained an interval estimate of 41.95% to 58.05%. What is the confidence level and...

Question 3 (8 points) 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 200 students and finds that 108 of them are receiving financial aid. Use a 90% confidence interval to estimate the true proportion of students who receive financial aid.

A university dean randomly selected 200 students and found that 102 of them were receiving financial aid. a) Calculate the 80% confidence interval for the true rate of students who receive financial aid. Interpret the result. b) Calculate the 90% confidence interval for the true rate of students who do not receive financial aids. Interpret the result. c) How large a sample size needed with 95% confidence to estimate the true rate of students who receive financial aid within 0.05....

23. Suppose a sample of n = 50 items is drawn from a population of manufactured products and the weight, X, of each item is recorded. Prior experience has shown that the weight has a probability distribution with 6 ounces and ơ-2.5 ounces. Which of the following is true about the sampling distribution of the sample mean if a sample of size 15 is selected? a) The mean of the sampling distribution is 6 ounces b) The standard deviation of...
