In a random sample of 12 adults from the United States, the mean waste recycled per person per day was 1.7 pounds and the standard deviation was 0.3 pound. Assuming that the sample is approximately bell-shaped construct a 90% confidence interval estimate for the mean waste recycled per day by all U.S. adults.
What is the Confidence Interval: ( nothing , nothing ) (round each interval limit to two decimal places)
The local waste management says that the mean waste recycled per person per day in your town is 1.8 pounds. Is your town better or worse than the nation or can you tell by the confidence interval you found?
A. Better because 1.8 is above the interval.
B. Worse because 1.8 is below the interval.
C. One cannot tell because 1.8 is within the interval.

Based on a random sample of 1140 adults, the mean amount of sleep per night is 8.56 hours. Assuming the population standard deviation for amount of sleep per night is 1.3 hours, construct and interpret a 90% confidence interval for the mean amount of sleep per night. A 9090% confidence interval is (nothing,nothing). (Round to two decimal places as needed.) Interpret the confidence interval.

Based on a random sample of 1080 adults, the mean amount of sleep per night is 8.41 hours. Assuming the population standard deviation for amount of sleep per night is 3.8hours, construct and interpret a 90% confidence interval for the mean amount of sleep per night. A 90% confidence interval is (nothing,nothing). (Round to two decimal places as needed.)
