Question

Jada M Myers · Accepted Answer

Final Answer : D, Explanation :  The difference between the sample mean and the population mean can be attributed to sampling error, which is a natural result of selecting a sample from a population. It is likely that the researcher's sample was not a perfect representation of the population, leading to the difference in mean number of arrests. Non-normal error, luck, and a lack of planning are less likely explanations for the difference.
