. The city of Edmonton, Canada recently completed an audit of abandoned bank accounts. An account is considered abandoned if it has not been accessed in the last 20 years. A random sample of 50 such accounts was collected and a 95% confidence interval for the true mean abandoned account balance was found to be (267.43, 1455.00) dollars. Which of the following statements is a correct interpretation of the 95 percent confidence level? (A) If many such samples of size 50 were taken, we would expect 95% of the intervals constructed to contain the mean balance of all abandoned bank accounts in Edmonton. (B) There is a 95% chance that the constructed confidence interval contains the mean balance of all abandoned bank accounts in Edmonton. (C) If another random sample of 50 abandoned bank accounts were taken, we would be 95% confident that the sample mean balance would fall between $267.43 and $1455.00. (D) If many such samples of 50 abandoned bank accounts were taken, we would expect 95% of…
Suppose the Statistics Department at TAMU wants to create a confidence interval for the proportion of students that get an A in Stat 303 this semester. In past semesters, the proportion has been around 0.50 (50%). The department wants an interval with a confidence level of 99% and a margin of error of 0.05. What sample size should they use? 1557 798 1121 664 It is impossible to determine.
1. In a study of perception, 110 men are tested and 24 are found to have red/green color blindness (based on data from USA Today). Assume that this was done in a simple random manner. A 95% confidence interval estimate of the proportion of all men with red/green color blindness was found to be 0.14 to 0.30. If we learn that the actual population proportion of men with red/green colorblindness is equal to 0.12, then what can we conclude? A. The confidence interval was wrong. B. We would need to see the sample data to make any conclusions Pick either answer A or B as your answer and show your work to go with it
Listed below are the amounts of net worth in millions of the 10 wealthiest celebrities in a certain country. Construct a 90% confidence interval.
