Explain the sampling strategy and potential bias for the following situations. A. a. Bob is wondering about people that use the Love Library. Bob stands outside the library and asks people walking by into the library questions. b. Alice wants to know how 7th graders and 8th graders at Lemon Grove Middle schools feel about mathematics they are learning. Alice gives numbers to each name of 7th and 8th graders learning mathematics. Alice uses these numbers to make an interval. With this interval, Alice uses a random number generator to produce the numbers, which will be associated with names. The names produced by this method will be the students Alice asks questions to.
