2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

Problem 1:
Early-Onset Dementia. Dementia is the loss of the intellectual and social abilities severe enough to
interfere with judgment, behavior, and daily functioning. Alzheimer's disease is the most common type
of dementia. In the article "Living with Early-Onset Dementia: Exploring the Experience and Developing
Evidence-Based Guidelines for Practice" (Alzheimer's Care Quarterly, Vol. 5, Issue 2, pp.111-122), P.
Harris and J. Keady explored the experience and struggles of peoples diagnosed with dementia and their
families. A simple random sample of 21 people with early-onset dementia gave the following normally
