A random sample of 67 lab rats are enticed to run through a maze, and a 95% confidence interval is constructed of the mean time it takes rats to do it. It is [2.3min, 3.1 min]. Which of the following statements is/are true? (More than one statement may be correct.) 95% of the lab rats in the sample ran the maze in between 2.3 and 3.1 minutes. 95% of the lab rats in the population would run the maze in between 2.3 and 3.1 minutes. Using the sample for these rats, about 95% of the time, the interval [2.3, 3.1] would contain the population mean. The true population mean is not known.

A random sample of 67 lab rats are enticed to run through a maze, and a 95% confidence interval is constructed of the mean time it takes rats to do it. It is [2.3min, 3.1 min]. Which of the following statements is/are true? (More than one statement may be correct.)

		95% of the lab rats in the sample ran the maze in between 2.3 and 3.1 minutes.
		95% of the lab rats in the population would run the maze in between 2.3 and 3.1 minutes.
		Using the sample for these rats, about 95% of the time, the interval [2.3, 3.1] would contain the population mean.
		The true population mean is not known.
