Conduct research to identify at least four different ‘divisibility rules’ that help you determine if one number is divisible by another certain number. For example, what divisibility rule will help you determine if a number is divisible by 10? List the rules that you identified in your research. Provide an example for each rule.

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
