What is the source of error when using a test tube?
A test tube (or sample tube) has no errors.
How Professionals Can Detect a Potential mold Problem?
A mold investigator is counsel-certified, having the know-how and experience to detect mold imaging machine, the inspector can create a comprehensive analysis. During this systematic inspection, the investigator looks for dampness and tests the quality of the air. Once spores have been detected, a sample will be analyzed under a microscope at a microbiology facility. The findings or account will be delivered to the client. Also included with the summary will be a consultation. This consultation involves helpful recommendations on remediation. The homeowner will not only gain information on how to put right the situation but will also learn ways of preventing a potential problem.

What are the techniques used in DNA sequencing?
A common approach to DNA sequencing is through a process called Sanger sequencing, named after its inventory, Frederick Sanger. To describe the process simply, a sample of purified DNA is treated with a solution of enzymes, nucleotides, and terminators to duplicate the strands of DNA. As the DNA is being copied, it uses the nucleotides to form new strands of DNA and sometimes will add a terminator which stops the duplication process at varying lengths. The terminators are labeled with a radioactive or fluorescent chemical which allows them to be detected by a scanning machine. In capillary electrophoresis, the mixture of varying length DNA is separated in a very narrow tube and as each terminator passes by the detector, the sequence of the DNA bases can be read. For a more detailed description of the mechanics of Sanger sequencing, an internet search will yield many results.

Can sabuxoen be detected in a urine sample?
Yes Suboxone can be detected in a urine sample. It can not however be detected in a standard drug test.
To cut the maximum likely error in half the sample size should be?
... should be increased by a factor of 4. Note that this implies that the only errors are statistical (random) in nature; increasing the sample size won't improve systematic errors.
What is the difference between simple random sampling and systematic random sampling?
simple random sample is to select the sample in random method but systematic random sample is to select the sample in particular sequence (ie 1st 11th 21st 31st etc.)• Simple random sample requires that each individual is separately selected but systematic random sample does not selected separately.• In simple random sampling, for each k, each sample of size k has equal probability of being selected as a sample but it is not so in systematic random sampling.
When taking a systematic random sample of size and n every group of size n from the population has the same chance of being selected?
That is not true. It is true for a simple random sample but not one that is systematic.

When can statistics be used to gain information about a population from a sample?
When the sample - whether it is random or systematic - is somehow representative of the population.

What does free fat detected in a mid stream urine sample mean?
Free fat detected in a mid stream urine sample just simply means that there was fat found in the urine sample. Free fat is just the term used when referring to free globules of fat in urine.
