10. A systematic sample of 1000 people across 10 states found that the average person generates 7.45 pounds of trash per day with a population standard deviation of 1.11 pounds. Determine if the information can be used to create a confidence interval. If so, find the 99% confidence interval. If not, give a detailed explanation as to why this information does not fit the definition

10. A systematic sample of 1000 people across 10 states found that the average person generates 7.445
pounds of trash per day with a population standard deviation of 1.11 pounds. Determine if the
information can be used to create a confidence interval. If so, find the 99% confidence interval. If
not, give a detailed explanation as to why this information does not fit the definition
11. It is thought that 36% of the United States population vote only for a single party. In the recent
election a random sample of 500 people in Tennessee were taken and it found that 225 have only
ever voted for a single party. Answer the following:
(a) Find the 94% confidence interval for the average percent of people in Tennessee who will only
ever vote for a single party
(b) If we wanted to ensure to keep the margin of error under 3%, how many people should we
survey?
(c) Based on your confidence interval, what can you say about voting patterns in Tennessee
compared to the United States?
