Suppose you are a researcher in a hospital. You are experimenting with a new tranquilizer. You collect data from a random sample of 9 patients. The period of effectiveness of the tranquilizer for each patient (in hours) is as follows: 2.7 2.6 2.7 2.3 2.3 2.4 2.6 2.4 2.4 What is a point estimate for the population mean length of time. (Round answer to 4 decimal places) Correct Construct a 99% confidence interval for the population mean length of time. Enter your answer as an open-interval (i.e., parentheses) Use a critical value rounded to three decimal places. Round upper and lower bounds to two decimal places. What does it mean to be "99% confident" in this problem? _________
I just need help with constructing the confidence interval please, thank you! Its the last question for this

What is a point estimate for the population mean length of time. (Round answer to 4 decimal places) Correct
Construct a 99% confidence interval for the population mean length of time. Enter your answer as an open-interval (i.e., parentheses) Use a critical value rounded to three decimal places. Round upper and lower bounds to two decimal places.
