Less time and less cost for a sample.
Sample is preferred to population because observing the population can be impossible due to its size. You take a random sample of the population and, with statistics, you can infer things about that population to various degrees of confidence based on the sample size and on other knowledge about the population. For instance, if you wanted to know how many people on earth have brown hair, you would not check all 6 billion people - you would create a sample set, say a few hundred, thousand, or whatever - count the number with brown hair - and then run your calculations.
Sampling can be more accurate than a census as there is greater control of interviewers and less chances of mistakes being made as the data is collated
It is composite.

Composite toe and steel toe safety shoes have the same function and meet the same standards, so they are interchangeable in most circumstances. Composite might be preferred to steel if you are working around electricity or in cold environments.
1) when the fixed cost of selecting a sample is high. 2) when there is high variability in the characteristic been measured. 3) when the population is small.
Urine is the preferred sample when testing for acidemia in metabolic disorders. The general researchers says that the metabolites appear in urine first and take longer to be detected in blood, making the urine sample as the preferred sample for screening and diagnosis of rare 100 metabolic disorders. Metabolites appear first in the urine and later in the blood, making pre-symptomatic detection of metabolic disorders possible from urine sample. Its a Non-invasive process for screening of metabolic disorders, hence its Baby-friendly. Therapy and Management of these disorders at its earliest will help to curb any damage to the baby.
This cannot be answered Until and Unless a certain set of numbers are given as Sample Space.
