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: Hours 2.5 3 2.9 2.8 2.7 2.3 2.8 2. 2.8 What is a point estimate for the population mean length of time. (Round answer to 2 decimal places) 2.64 What must be true in order to construct a confidence interval in this situation? The population must be approximately normal Construct a 98% confidence interval for the population mean length of time. (Round the critical value to 3 decimal places. Round upper and lower bounds to 2 decimal places.) What does it mean to be "98% confident" in this problem? 98% of all confidence intervals found using this same sampling technique will contain the population mean time. O There is a 98% chance that the confidence interval contains the sample mean time.
