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%). 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.

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?
