Foot Sample
When chemical carriers load high value and very pure products, they will commence loading until about one foot of cargo is in the bottom of the tank, then stop. They will take a sample this cargo, known as the foot sample up the facility's lab for analysis to see if during the loading of this one foot of cargo there was any contamination. If not, they will resume loading the tank until completion. If contamination is present in the foot sample they will try to determine the source, while they pump the now off spec cargo to the shore, and start over again, It is hoped that the amount loaded during the foot of cargo is enough to clean the contamination from the tank and piping. This is done to prevent the entire tank being loaded and then contaminated thereby requiring the full cargo to be reprocessed.

What is the formula for calculating the mean of a sample, represented by the symbol "" in statistics?
The formula for calculating the mean of a sample, represented by the symbol "" in statistics, is to add up all the values in the sample and then divide by the total number of values in the sample. This can be written as: x / n, where x represents the sum of all values in the sample and n is the total number of values in the sample.
A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 9?
To test the hypothesis that the mean weight is 6.6 pounds, you could use a one-sample t-test on the sample data. The one-sample t-test will help determine if the mean weight of the sample is significantly different from 6.6 pounds based on the data collected.
What is the single quantity compared to an entire sample?
The single quantity compared to an entire sample is called a statistic. It is a numerical measurement calculated from the data in the sample, such as the mean, median, or standard deviation. The statistic provides insight into the characteristics or properties of the sample as a whole.
What does dorsiflexion mean?
Dorsiflexion is the movement of bending the foot upwards at the ankle, bringing the top of the foot closer to the shin. This movement decreases the angle between the foot and the shin. It is the opposite of plantarflexion.
What is the significance of the symbol in statistical analysis?
The symbol represents the mean of a sample in statistical analysis. It is significant because it helps to estimate the population mean and understand the central tendency of the data.
What do the signs on the chemical tankers mean?
Do Google search for "DOT Placards".
What does PB sample mean in medical terminology?
Pb is the chemical abbreviation for lead, so perhaps it refers to a sample taken for lead level testing.
What happens to the sample mean as the sample size increases?
With a good sample, the sample mean gets closer to the population mean.
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
When using the distribution of sample mean to estimate the population mean what is the benefit of using larger sample sizes?
The variance decreases with a larger sample so that the sample mean is likely to be closer to the population mean.
A Numerical Measure from a Sample Such as a Sample Mean Is Known?

What is the difference between calculating the sample mean and the population mean?
You calculate the actual sample mean, and from that number, you then estimate the probable mean (or the range) of the population from which that sample was drawn.
What is the estimated population mean with a sample of 36 and a standard deviation of 0.03?
What is the sample mean?
Why is the sample mean an unbiased estimator of the population mean?
The sample mean is an unbiased estimator of the population mean because the average of all the possible sample means of size n is equal to the population mean.
What information about a sample does a mean not provide?

What is population mean in statistics?
The population mean is the mean value of the entire population. Contrast this with sample mean, which is the mean value of a sample of the population.
What is a purposive sample?
Propulsive Sampling Mean a sample which we can take randomly
