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 mninutes. DUsing the sample for these rats, about 95% of the time, the interval [2.3, 3.1] would contain the population mean. O The true population mean is not known. QUESTION 2 The IQ test has a mean of 100 and a standard deviation of 15. Suppose a simple random samnple of 150 students take an IQ test. What is the standard error for this sample? (Round to hundredth). QUESTION 3 The national IQ test has a mean of 100 and a standard deviation of 15. Suppose a simple random sample of 150 students take an 1Q test and the sample mean is 112. What is the lower bound for this 90% confidence interval level for this sample? (Round to hundredth). QUESTION 4 The national 1Q test.has a mean of 100 and a standard deviation of 15. Suppose a simple random sample of 150 students take an IQ test and the sample mean is 112. What is the upper bound for this 90% confidence interval level for this sample? (Round to hundredth).
