A golf instructor claims that more than 70% of his students have improved their driving distance by at least 20 yards after viewing and applying the techniques described in his instructional video. If 138 out of 180 viewers say that their driving distance has improved by at least 20 yards, is the instructor's claim valid? Identify the null and alternative hypotheses for this scenario. Is the instructor's claim that "more than 70% of his students have improved their driving distance by at least 20 yards," valid? Your response should include your decision and conclusion in context of the scenario.
