The U.S. Energy Information Administration (US EIA) reported that the average price for a gallon of regular gasoline is $3.95. The US EIA updates its estimates of average gas prices on a weekly basis. Assume the standard deviation is $.24 for the price of a gallon of regular gasoline and recommend the appropriate sample size for the US EIA to use if they wish to report each of the following margins of error at 95% confidence. Round up to the next whole number.a. The desired margin of error is $.10. The appropriate sample size is ____.b. The desired margin of error is $.06. The appropriate sample size is ____.c. The desired margin of error is $.04. The appropriate sample size is _____.

Sleep apnea is a disorder in which there are pauses in breathing during sleep. People with this condition must wake up frequently to breathe. In a sample of 427 people aged 65 years and older, 104 of them had sleep apnea. a) Find a Point Estimate for the proportion of people aged 65 years and older who have sleep apnea. Round to 2 decimal places. b) Use your calculator to construct a 99% Confidence Interval. Indicate your basic keystrokes and round your interval to 2 decimal places. c) Interpret your Confidence Interval. In another study, medical researchers concluded that about 15% of elderly people have sleep apnea. Use your confidence interval from part "b" to explain why that does or does not seem

In a random sample of 8 people, the mean commute time to work was 33.5 minutes and the standard deviation was 7.2 minutes. A 95% confidence interval using the t-distribution was calculated to be (27.5 comma 39.5 ). After researching commute times to work, it was found that the population standard deviation is 9.5 minutes. Find the margin of error and construct a 95% confidence interval using the standard normal distribution with the appropriate calculations for a standard deviation that is known. Compare the results.
