„An online used car company sells second- hand cars. For 30 randomly selected transactions, the mean price is 2800 dollars. Part a) Assuming a population standard deviation transaction prices of 130 dollars, obtain a 99% confidence interval for the mean price of all transactions. Confidence interval: ( Part b) Which of the following is the correct interpretation for your answer in part (a)? A. If we repeat the study many times, 99% of the calculated confidence intervals will contain the mean price of all transactions.
