Statistics question 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 yoursample is biased? Explain. What else could have caused this high mean?Choose the correct answer below.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.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.

Sampling bias: Sampling bias occurs when a certain part of the population is favoured more into the sample than the other part. It mainly occurs when a sample is selected, which does not represent the population. As the sample size increases, we can obtain more information regarding the variable which will reduce the variability.It is given that the sample mean is higher than the population mean. The sample mean is based on 3 observations. Here, the sample may not be biased. The high mean might have occurred by chance, since the sample size is very small. Correct answer is option (A).
