How many minutes is 46 miles?
That cannot be properly answered unless you specify how fast you are traveling.
What are the disadvantages of non-representative sampling?
The sample is of little use in making estimates for the population as a whole unless it is known exactly how it is non-representative.
How do we calculate tree volume if the height is not known?
If you cannot estimate the height then, unless it is a very specific shape, you cannot calculate the volume.
When you give a urine sample at the pediatrician do they routinely check for pregnancy?
not usually unless they prescribe you a medication that you cannot take while pregnant; or if your doing a physical
What is the probability of selecting a composite number over a prime number?
This cannot be answered Until and Unless a certain set of numbers are given as Sample Space.
Does Ritalin show up on the standard five point drug test?
No it will not. It is METHYLPHEDATE and cannot be detected unless it is sent to a lab.
Does fresh water have magnesium and silicon?
Unless it is "deionized water" fresh water will contain dissolved minerals. Both magnesium and silicon are likely to be in those dissolved minerals, but I cannot state with certainty if a given water sample contains them unless it has been chemically analyzed.

What are the number of sulfur atoms in a sample of 21.6 g of mercury1 nitrate?
Mercury I nitrate does not contain sulfur unless the sample is contaminated.
What is rate measure and calculation of errors?
Standard error (statistics)From Wikipedia, the free encyclopediaFor a value that is sampled with an unbiased normally distributed error, the above depicts the proportion of samples that would fall between 0, 1, 2, and 3 standard deviations above and below the actual value.The standard error is a method of measurement or estimation of the standard deviation of the sampling distribution associated with the estimation method.[1] The term may also be used to refer to an estimate of that standard deviation, derived from a particular sample used to compute the estimate.For example, the sample mean is the usual estimator of a population mean. However, different samples drawn from that same population would in general have different values of the sample mean. The standard error of the mean (i.e., of using the sample mean as a method of estimating the population mean) is the standard deviation of those sample means over all possible samples (of a given size) drawn from the population. Secondly, the standard error of the mean can refer to an estimate of that standard deviation, computed from the sample of data being analyzed at the time.A way for remembering the term standard error is that, as long as the estimator is unbiased, the standard deviation of the error (the difference between the estimate and the true value) is the same as the standard deviation of the estimates themselves; this is true since the standard deviation of the difference between the random variable and its expected value is equal to the standard deviation of a random variable itself.In practical applications, the true value of the standard deviation (of the error) is usually unknown. As a result, the term standard error is often used to refer to an estimate of this unknown quantity. In such cases it is important to be clear about what has been done and to attempt to take proper account of the fact that the standard error is only an estimate. Unfortunately, this is not often possible and it may then be better to use an approach that avoids using a standard error, for example by using maximum likelihood or a more formal approach to deriving confidence intervals. One well-known case where a proper allowance can be made arises where Student's t-distribution is used to provide a confidence interval for an estimated mean or difference of means. In other cases, the standard error may usefully be used to provide an indication of the size of the uncertainty, but its formal or semi-formal use to provide confidence intervals or tests should be avoided unless the sample size is at least moderately large. Here "large enough" would depend on the particular quantities being analyzed (see power).In regression analysis, the term "standard error" is also used in the phrase standard error of the regression to mean the ordinary least squares estimate of the standard deviation of the underlying errors.[2][3]
