Could you help me with these stats questions? Thank you so much. 1. As a researcher for a pharmaceutical company, you are designing a study to test the effectiveness of a new treatment for pet allergies. You have been given a list of 252 people willing to participate in the trial. Of the 252 participants, 176 are female and the remaining are male.

Part APreliminary research suggests that men and women respond differently to this new treatment. What sort of experimental design would you choose for this study, and why?

Part BDescribe a complete design for this experiment. Be sure to clearly describe how you would measure your variables, determine treatment groups, the assignment of individuals to treatment groups, and conclusions you could base on your results.

2.For each study described below, comment on the extent to which inferences can be drawn about a larger population and whether cause and effect can be established.

Part AA basketball coach thinks lessons in dance will improve the agility of his players and thereby reduce injuries. To test his theory, he hosts an optional weekly dance practice for any of his players that wish you participate. At the end of the season, he compares agility for those athletes who participated in dance training and those who did not.

Part BA student wishes to determine if staying up all night "cramming" for an exam improves performance. She explores this question by asking everyone in her Calculus class to write down on a piece of paper his or her score on a recent test and total number of hours of sleep he or she got on the last three nights before taking the test.

Part CDoes Lysine, a popular over-the-counter cold sore remedy that claims to reduce the length and severity of cold sores really work? A consumer advocacy group addresses this question by asking a random sample of 250 adults how many cold sores they'd had in the last six months, how long each cold sore lasted, and if they took Lysine to treat the cold.
