QUESTION #6

In October 2017, an outbreak of mumps had occurred on campus. 57 students of the Class of 2020 were exposed to this childhood disease. Surprisingly, only 43 of the students had received the two needed doses of MMR vaccine which protects against the disease - which makes you concerned about the declining rater of necessary childhood vaccinations in the state of Jefferson. In the past, from a sample of 100 JSU students from the Class of 2010 who had had mumps as a child, 83% of them had the recommended two doses of the vaccine. Test the hypothesis that the MMR vaccination rate for the two groups is different at = 0.05.
