Answer: 0.5
Explanation:
Number of people with traits = 900
Total number of individuals= 1800
To find the probability with regards to the question, we divide the number of individuals having the traits by the total population of individuals. This will be:
= 900 / 1800
= 0.5

Answer:
The comparison of a measurement with a known standard, used to determine whether the measurement is reliable. Measurement accuracy is identified as the difference between the measurement of a factor and the accepted value for that factor from a trusted external source, or the percentage by which the two values differ.
Explanation:
In the context of scientific approach, the role of data is central as well as fundamental when scientists search for observations which would either verify or reject their ideas regarding the world.
The scientific approach follows a systematic order in which theories or hypotheses are tested through experiments and observations are recorded. These observations are in the form of raw data which are then analyzed by scientists.
Analysis of the data leads to the generation of information which can be utilized suitably to develop an insight about the subject of interest. This information is helpful in determining whether an idea or theory is substantial or not.
