- A college admissions director wishes to estimate the mean age of all students currently enrolled. In a random sample of 30 students the mean age is found to be 21.5 years. From past studies the population standard deviation at the college is known to be 1.2 years and the population is normally distributed. Construct a 95% confidence interval of the population median age.The average number of pages per book from a library is unknown. A random sample of books from the library yields a sample mean of x¯=149.7 pages. Assume the sampling distribution of the mean has a standard deviation of σx¯=14.1 pages. Use the Empirical Rule to construct a 99.7% confidence interval for the true population mean number of pages.Suppose that the height of Asian males aged 35-44 in the United States is normally distributed with a standard deviation of 3 in. Jeremy takes a simple random sample of 16 such men and notices that none of them are unusually tall or unusually short. He then calculates the average of the sample to be 67 in. and is planning on using this to find a 90% z-confidence interval for the true mean height. Can Jeremy use this information to find the z-confidence interval? Complete the following sentences. The population distribution is and the population standard deviation is Therefore, the sample to find a 90% z-confidence interval.

- An agriculture publication claims that the population mean of the birth weights for all Herdwick sheep is 4.62 kg. A veterinary service has hired you to test that claim. To do so, you select a random sample of 35 Herdwick sheep and record the birth weights. Assume it is known that the population standard deviation of the birth weights of Herdwick sheep is 2.15 kg. Based on your sample, follow the steps below to construct a 95% confidence interval for the population mean of the birth weights for all Herdwick sheep. Then state whether the confidence interval you construct contradicts the publication's claim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results from your random sample of 35 Herdwick sheep. (b) Take Sample Sample size: Point estimate: Population standard deviation: Critical value: Compute 0.00 0.00 Number of sheep 35 Enter the values of the sample size, the point estimate for the population mean, the population standard deviation, and…Assume that a sample is used to estimate a population mean. Find the 90% confidence interval for a smaple of size 46 with a mean of 68.5 and a standard deviation of 6.6.
