Tou are experimenting With a new tranquilizer. rou collect uala from a random sample of 8 patients. The period of effectiveness of the tranquilizer for each patient (in hours) is as follows: Hours 2 2.4 2.3 2.3 2.3 2.9 2 2.9 What is a point estimate for the population mean length of time. (Round answer to 2 decimal places) What must be true in order to construct a confidence interval in this situation? Select an answer Construct a 90% 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 "90% confident" in this problem? The confidence interval contains 90% of all sample times. 90% of all times will fall within this interval. O There is a 90% chance that the confidence interval contains the sample mean time. 90% of all confidence intervals found using this same sampling technique will contain the population mean time
