Show all steps in all calculations, including numerators and denominators, and include multipliers in all final answers. Problem 1: Prevalence of Students with Gastroenteritis (6 points, 2 points each) Consider a class with 100 enrolled students. None of the students were ill at the beginning of the school year. On September 30, a total of 5 students reported having gastroenteritis. All 5 continued to be ill on October 1, but all 5 recovered within 3 days. On October 14, another...
