I am very confused on how to work through these problems.
1) Calculate a 95% confidence interval with a population mean of 25, population standard deviation of 5, and sample population of 100.
2) Calculate the population confidence interval with a mean of 5, a sample size of 500, a confidence level of 95%, and a standard deviation of 4. How does a larger standard deviation affect the calculation of a confidence interval? Why is this so?
3) Calculate the population confidence interval with a mean of 5, a sample size of 1,000, a confidence level of 95%, and a standard deviation of 2. How does a larger sample size affect the calculation of a confidence interval? Why is this so?
4) Calculate the population confidence interval with a mean of 5, a sample size of 500, a confidence level of 90%, and a standard deviation of 2. How does a lower confidence level affect the calculation of a confidence interval? Why is this so?
