CRO Suppose you are a researcher in a hospital You are experimenting with a new sedative You collect data from a random sample of 13 patients The period of effectiveness of the sedative for each patient in hours is as follows Hours 2 3 2 7 2 7 2 4 2 6 2 5 2 2 4 2 4 2 2 4 3 2 8 a What is a point estimate for the population mea length of time Round answer to 4 decimal places b What must be true in order to construct a confidence interval in this situation Select an answer c Construct a 95 confidence interval for the population mean length of time Enter your answer as an open interval i e parentheses example 5 2314 8 1245 Round upper and lower bounds to 4 decimal places d What does it mean to be 95 confident in this problem 0 95 of all confidence intervals found using this same sampling technique will contain the population mean time O95 of all times will fall within this interval O The confidence interval contains 95 of all sample times O There is a 95 chance that the confidence interval contains the sample mean time e Suppose that the company releases a statement that the mean time for all patients is 2 hours
