Suppose that, when taking a random sample of three students' GPAS, you get a sample mean of 3.90. This sample mean is far higher than the college-wide (population) mean. Does this provide that your sample is biased? Explain. What else could have caused this high mean? Choose the correct answer below. O A. The sample may not be biased. The high mean might have occurred by chance, since the sample size is very small. O B. Nothing other than bias could have caused this small mean. O c. One or more of the students could have lied about their GPAS. O D. The sample may not be biased. The measurements may not have been precise.
