a.) What is the appropriate test procedure to be used?b.) What are the set of hypotheses?c.) Considering the p-value, would their be sufficient or insufficient evidence that a particular behavior will indeed occur more often during the full moon? The most widely believed myth about the full moon is that it causes strange behavior. A social scientistconducted a study to determine if a particular behavior will indeed occur more often during the full moon. Twoweeks before the full moon in April, 15 couples residing in Luna Condominium were randomly selected andasked to observe if they were engaged in a conflict on that day. They were also monitored through CCTV toverify their reported behavior. On the day of the full moon, another random sample of 15 couples residing in theadjacent condominium building were also asked to observe if they were engaged in a conflict. Their reportswere also verified through CCTV.Consider di = Xday – Xtwoweeks Where Xday is the number of couples who were engaged in a conflict on the day ofthe full moon and Xtwoweeks is the number of couples who were engaged in a conflict two weeks before the fullmoon.R COMMANDER OUTPUT #3.1Frequency table:fightfull.moonOn the dayTwo weeks beforeYesNo Total9.6157815R COMMANDER OUTPUT #3.2X-squared = 0.13393, df = 1, p-value = 0.7144alternative hypothesis: two.sidedX-squared = 0.13393, df = 1, p-value = 0.3572alternative hypothesis: greater= 0.13393, df = 1, p-value = 0.6428X-squaredalternative hypothesis: less

Exercises 1–5 refer to the sample data in the following table, which summarizes the last digits of the heights (cm) of 300 randomly selected subjects (from Data Set 1 “Body Data” in Appendix B). Assume that we want to use a 0.05 significance level to test the claim that the data are from a population having the property that the last digits are all equally likely. What are the null and alternative hypotheses corresponding to the stated claim?
