Mrs. Greer was making pancakes for breakfast. Baking is an exact science so correct measurements are crucial. She had a recipe that called for 1 1/2 cups of water for 2 cups of mix. She only had 1 1/2 cups of mix. How much water should she add as a fraction, since her measuring cup only has fractions. (This is a true story, I actually did this on Sunday, only an exact fractional answer will count)

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?
