The ideal length of a metal rod is 28.5 cm. The measured length may vary from the ideal length by at most 0.045 cm. What is the range of acceptable lengths for the rod? A. x ≤ 28.455 or x ≥ 28.545 B. 28.455 ≤ x ≤ 28.545 C. 28.455 ≥ x ≥ 28.545 D. 28.455 ≤ x ≥ 28.545

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?
