Calculate the net death rate for the year based on the following statistics: 15,567 discharges with 245 deaths (75 deaths occurr
1 answer:
Answer:
13665.6 deaths per year
Step-by-step explanation:
We can determine certain statistics based on the information. If 15567 patients where discharge and 245 deaths were recorded, the total number of patients were:
If 75 deaths occured in the first 48 hours we have a death rate of:
1.56 deaths per hour.
We want the death rate per year. If we have the death rate per hour we can determine the death rate per year:
[tex]1.56\cdot{24}\cdot{365}=13665.6[tex]
13665.6 deaths per year

Step-by-step explanation:
The x-coordinate of the accident is a random variable of uniform distribution with range [-1.5,1.5]. The same can be said for the y-coordinate. However, |x| and |y| are also uniform variables with range [0,1.5], since we still have the same probability on every pair of intervals with the same lenght.
Note that |X| and |Y| are independent with each other, therefore E(|x|+|y|) = E(|x|) + E(|y|) = 2*E(|x|). The last equality holds because both x and y are identically distributed, then so are |x| and |y|.
E(|x|) =
Therefore, E(|x| + |y|) = 2 * 3/2 = 3.
