the top tour of these accounting for over 50% of all non-accidental deaths as follows: heart disease (23.4%), cancer (22.5%), respiratory disease (5.6%), and stroke (5.1%). To test the goodness-of-fit of these proportions, a study of the causes of n = 308 non-accidental deaths at a local hospital gave the following counts. Cause Heart Disease Cancer Respiratory Disease Stroke Other 28 Deaths 78 81 16 105 1. Find the expected number of deaths due to Cancer. 2. Find the chi-square test statistic. 3. Find the p-value at level of significance a = 0.05. Do the data provide sufficient infor- mation to indicate that the number of deaths at this hospital differ significantly from the proportions in the population at large?

Q4: Nearly 75% of all deaths in USA are attributed to just 10 causes, with the top tour of these accounting for over 50% of all non-accidental deaths as follows: heart disease (23.4%), cancer (22.5%), respiratory disease (5.6%), and stroke (5.1%).
