Medical statistics show that deaths due to four major diseases - call them A, B, C and D - account for 15%, 21%, 18%, and 14%, respectively, of all non-accidental deaths. A study of the causes of 616 non-accidental deaths at a hospital give the following counts: Do these data provide sufficient evidence to indicate that the proportions of people dying of diseases A, B, C, and D at this hospital differ from the proportions accumulated for the population at large?
Find the approximate p-value and use it to make your decision.
Compute :
______________
Reject when > ______________.
Thus the p-value ______________.
Conclude that the proportions of people dying of diseases A, B, C, and D at this hospital ______________ from the proportions for the larger population.
Non-accidental Deaths
Refers to deaths resulting from causes other than accidents, such as diseases or intentional harm.
