What else can I help you with?
What temperature should urine be at for a drug test to be considered valid?
Urine for a drug test should be between 90-100 degrees Fahrenheit to be considered valid.
What temperature should urine be for a drug test to be considered valid?
Urine temperature for a drug test to be considered valid should be around 90-100 degrees Fahrenheit.
Why do you fail a drug test if your urine is cold?
A freshly collected sample of urine will be near body temp. A bottle of someone else's urine (that does not do drugs) in your pocket will not be as warm. If the temp of a sample is very low, it is not considered to be a valid sample from THAT person.
Will urine still be tested if the temperature isn't right?
If temperature is being used to verify that the urine came from the correct person the temperature of the sample is an indicator that the urine is/may not be a fresh/valid sample...if the temperature is lower than expected.
Is a biased sample always valid?
a biased sample is valid determin
Is 100 degrees to hot for a urine sample?
Yes. A urine sample home-test should be 89.6 - 98.6 Fahrenheit (32-37 Celsius). If the pee is too hot or too cold, the test will be deemed invalid and the test will show blank (N/A). This will cause whoever is demanding you to take the test, to know that you either faked it with someone's urine, that is not yours. (You can explain this by "I have a fever" for example) With a test at your local doctors they will use the same method as in the home-test, whilst in bigger cases it will be sent for deeper research in a laboratory. (For example deeming if your statement of being affected by drugs while murdering a man, is valid or non-valid) Here the temperature the urine is at any point of time, won't be necessary to think about. Hope this helped you. Best of luck with whatever law your thinking about breaking!
When the sample size is large valid confidence intervals can be established for the population mean irrespective of the shape of the underlying distribution?
Yes, but that begs the question: how large should the sample size be?
Why is obtaining a representative sample important?
Many statistical statements for a population which are based on a sample are not valid if the sample is not representative.
Is a simple random sample valid?
Yes, a simple random sample is considered valid as it ensures that every member of the population has an equal chance of being selected. This randomness helps eliminate bias and allows for generalizations to be made about the larger population based on the sample. However, the validity of the results also depends on the sample size and the proper execution of the sampling method. Properly conducted, it provides a reliable foundation for statistical inference.
What conditions are required to form a valid large-sample confidence interval for you?
1) What conditions are required to form a valid large-sample confidence interval for µ?
Why is it important to have a representative sample when doing surveys?
Because without representative sample, your results will not be valid.
Which conditions may be met for a scientifically valid sample?
at random to represent the population
