Can you please help me. I am stuck stuck on the last two questions
Suppose you are a researcher in a hospital. You are experimenting with a new tranquilizer. You collect data from a random sample of 11 patients. The period of effectiveness of the tranquilizer for each patient (in hours) is as follows: Hours 2.4 2.1 2.7 2.4 2.6 2.5 2 2.1 2.7 What is a point estimate for the population mean length of time. (Round answer to 2 decimal places) 2.41 What must be true in order to construct a confidence interval in this situation? The population must be approximately normal Construct a 95% 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.) 1.6747 3.1453
