As part of an investigation into health service funding, concerns were raised with the issue of
whether sickness rates could be used to predict mortality rates. Data on standardized mortality
rates and standardized sickness rates were collected for a sample of 10 regions and are shown
in the table below:
Region Mortality Rate (per
10,000)
Sickness Rate (per 1,000)
1 125.2 206.8
2 119.3 213.8
3 125.3 197.2
4 111.7 200.6
5 117.3 189.1
6 100.7 183.6
7 108.8 181.2
8 102.0 168.2
9 104.7 165.2
10 121.1 228.5
a. Find the linear fitted regression equation of sickness rate on mortality rate
b. Interpret the intercept and the slope coefficients
c. Compute the Correlation Coefficient and the Coefficient of Determination based on
given data values. Be sure to show all the steps you used to arrive at your final answer.
d. Use your model to predict how the mortality rate will charge be impacted if 1200 patient
were admitted to hospital with the flu
