#1: A student named Leo is in the process of testing different types of greenhouse material so that he can determine which type is most effective for growing strawberry bushes; thus, he purchases two different brands of tarps from a local store, and applies brand A to an area of the yard that receives full sunlight whilst applying brand B to another area of the yard which is in partial shade. Leo waters both areas daily, and at the end of the study, he concludes brand A is the more effective one at growing strawberry bushes. Is his conclusion valid, and why or why not?

#2: There is a football quarterback who enjoys practicing his long passes over 40 yards. He unfortunately misses the first pass 40% of the time.
