Assume you are a member of the family research Council and have become increasingly concerned about the drug use by professional sports players. You set up a plan and conduct a survey on how people believe in the American culture (television, movies, magazines and popular music) influence illegal drugs use. Your survey consists 2259 adults and adolescence from around the country. A consumer group petitions you for more information about your survey. Answer the following questions about your survey using the APA format for citation and writing.
1. What type of survey did u used and why?( phone, mail, or interview)
2. What are the advantages and disadvantages of the surveying methods you did not used.
3. What type of score did you use why?
4. Did you use a random method for deciding who will be in your sample?
5. Which of the method ( stratifies, systematic, cluster, or convenience) did you use
6. Why was the method more appropriate for this type of data collection?
7. If a convenience sample were obtained, consisting of only adolescents, how would the results of the study be affected?

Explain the spectroscopic data of diatomic iodine
: The spectroscopic data of diatomic iodine shows a vibrational frequency of 214.5 cm-1, rotational constant of 0.03737 cm-1, and D0 of 12,440 cm-1. If the enthalpy of reaction is 153.97 KJ, Does this value make sense based on the spectroscopic data..

Explain the first two electronic states
: For atomic iodine, determine the degeneracy (which arises from the spin multiplicity) of the first two electronic states. Both are derived from the same S-L term symbol, using spin-orbit (J) coupling. The second state lies 7580 cm-1 above the firs..
