Suppose you send out 350 surveys to random sample of all past customers (your target population) asking them to report their level of satisfaction with your product. Of the 350, you used the 112 that responded to the survey to construct a confidence interval for the population "satisfaction score." What might be a potential problem with this confidence interval?
A) Predictable-world bias
B) Satisfaction scores are inherently variable.
C) There is likely to be skewness in the sample.
D) The sample you're using is not a random sample from the target population.
