In a study of woman's bone health, a random sample of 8 women was taken, and their daily calcium intake measured. The sample mean was 926 milligrams, and the sample standard deviation was 427.2 milligrams. What is the upper limit of a 99% confidence interval for the mean daily calcium intake of all women?
A quality control inspector selects 12 bottles of apple juice at random from a single day’s production. The mean amount of apple juice in the bottles is 298.3 milliliters, and the 95% confidence interval for the true mean amount of juice dispensed per bottle is (296.4, 300.2). Does this interval give the quality control inspector reason to believe that the mean amount of juice in today’s bottles differs from 300 milliliters, as the juice label promises? Yes, since the sample mean of 298.3 ml is less than 300 ml. Yes, since nearly the entire confidence interval is less than the advertised value of 300 ml. No, since the sample mean of 298.3 ml is in the confidence interval. No, since the advertised value of 300 ml is in the confidence interval.
A study of 420,007 cell phone users found that 136 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0319% for those not using cell phones. Complete parts (a) and (b). Use the sample data to construct a 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system. b. Do cell phone users appear to have a rate of cancer of the brain or nervous system that is different from the rate of such cancer among those not using cell phones? Why or why not?
In a survey of 74 US females, 56 said they had gone to the dentist within the past year. What is the UPPER endpoint of a 95% confidence interval for the population proportion? What is the LOWER endpoint of a 95% confidence interval for the population proportion?

A poll reported that only 1316 out of a total of 1746 adults in a particular region said they had a "great deal of confidence" or "quite a lot of confidence" in the military. Assume the conditions for using the CLT are met. Complete part (a) (a) Find a 95% confidence interval for the proportion that express a great deal of confidence or quite a lot of confidence in the military, and interpret this interval. The 95% confidence interval for the proportion that express a great deal of confidence or quite a lot of confidence in the military is: ( ? , ? )
