Research Study #2 for a Hypothesis Test Odetunmubi et al. (2021) described how Hepatitis B is a serious medical condition that impacts the liver and reduces an individual's immune response to infection. The research team wanted to understand the demographics of patients with Hepatitis B. To study this question, the medical records of patients diagnosed with Hepatitis B were reviewed and the age of patients at first diagnosis was recorded. Patients were grouped into three age categories: 21-30, 31-40, and 41-50 years old. Odetunmubi et al. wanted to know if there is a preference in age categories; in other words, the researcher wants to know if an age group(s) has/have more Hepatitis B diagnoses. There was a total of 144 patients (N = 144) who participated in the study. You will conduct the hypothesis test on Research Study #2. The ten (10) questions below will ask about the different parts of the hypothesis test. Calculate E (expected frequencies) for the three groups (clearly indicate the E for each group)
