"a seed randomly blows around a complex habitat. it may land on any of three different soil types: a high-quality soil that gives a 0.8 chance of seed survival, a medium-quality soil that gives a 0.3 chance of survival, and a low-quality soil that gives only a 0.1 chance of survival. these three soil types (high, medium, and low) are present in the habitat in proportions of 30: 20: 50, respectively. the probability that a seed lands on a particular soil type is proportional to the frequency of that type in the habitat. a. draw a probability tree to determine the probabilities of survival under all possible circumstances. b. what is the probability of survival of the seed, assuming that it lands"c. assume that the seed has a 0.2 chance of dying before it lands in a habitat. what is its overall probability of survival?

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?
