The data can be found in data set provided before starting the exam. Use the sheet: Study Hours.   A. Estimate, with 95% confidence, the population mean number of hours spent studying per week for RIT students. Show the Minitab output. B. Provide a one sentence statistical interpretation of the confidence interval in the context of the problem. [5 points] C. Determine if the normality assumption has been met. Use one sentence to clearly state your answer and explain how you came to your conclusion. You do not need to show supporting output but rather explain what you did. [5 points] D. Do we have 95% confidence that the population mean number of hours RIT students study per week is at most 20 hours? Use one complete sentence to explain your answer. [4 points]  

Devan Sacks, age 12, is a new client in the dental practice and has been scheduled for dental hygiene care.  Devan is in the 7th grade, is one of the star players on the girls’ soccer team and wears an athletic mouth guard protector.  She is accompanied by her mother, Margaret, age 32, and her sister Bridget, age 10.  After completing health, dental and dental hygiene histories, the dental hygienist assesses the teeth, periodontium, and oral self-care skills.  Significant findings include gingival inflammation, bleeding on probing around some teeth, and poor oral hygiene.  Client has a knowledge deficit regarding biofilm, periodontal disease process, and personal oral health status.  If Devan participates in care planning, gives informed consent, assumes personal responsibility for oral health, and performs daily oral hygiene behavior effectively, one could say that her human need for_____________ is met.
