Hi,
I will start off with infections.

What is probably known is the infection rate in a given city in a hospital. This would be our population. What we can then do is collect data on the number of infections in our specific hospital. This would be our sample.

We can then tabulate a z-test to see if our hospital has significantly more or less infections then the population.

Accurate interpretation:

As I mentioned above, we are not sure if the hospital has less or more infections then the general population. Since we are not sure of how the results will turn out, this is called a non-directional hypothesis, and would need a two-tailed hypothesis testing.

Let's set our significance level to 0.05. In a one tailed test, our rejection region is on only one side of the bell curve, and would be 5% of 0.05. However, in this example, the rejection region must be split between both tails of the distribution?.025 in the upper tail and .025 in the lower tail?because your hypothesis specifies only a difference, not a direction.

For a 2-tailed test, you will reject the null hypotheses of no difference if the incidence of infection either much higher or much lower. In a ...

#### Solution Summary
