The answer is The Doppler Effect. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.
During any outbreak or whenever problems occur, there are
always three major steps to take.
1. First, is the containment action. In this step, actions
are taken to reduce or lessen the severity of the people affected. This aims in
isolating the disease. In this step, scientific knowledge is used in making
decision on what containment actions to take.
2. Second is the corrective action. This step focuses
solely on formulating medicine to treat the disease. Once again scientific
knowledge is used in creating those medicines.
3. Third is the preventive action. To prevent this disease
outbreak from recurring, certain actions are made to ensure this does not
happen again.
Answer: 20 ± 11.32
Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.
For the data set 2, z-value for 95% confidence interval is z = 1.96
Formula to calculate CI is
x ± 
where
x is mean
z is z-value
s is standard deviation
n is the sample number
Then:
20 ± 
20 ± 
20 ± 
20 ± 11.32
The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.
Sample Response:
Bacteria are helpful because they produce oxygen, which our bodies need to breathe, and they help us to digest the food we eat. Bacteria are also helpful because they are used in medicine to help us overcome disease. Bacteria are harmful because they can cause tooth decay and illnesses that can be either common or quite serious.
This is a sample response, so it's 100% correct. Peace!
