What is meant by 99 percent assay of ethyl acetate?
That is the concentration of the compound within a solvent. It's basically the purity of your sample of the compound (in this case ethyl acetate). So it could be equal to or greater than 99% ethyl acetate and the rest would be ethanol or some chemical that the ethyl acetate is dissolved in.
How could you get a sample if soluble salt?
A saline sample is salt water. Evaporate the water away, and salt crystals will be left behind.
A student investigated the physical and chemical properties of a sample of an unknown gas and then identified the gas Which statement represents a conclusion rather than an experimental observation?
B. The gas is carbon dioxide.
A procedural change would be required if a student wanted to determine the acidity of tomato juice by titrating a juice sample with NaOH solution Briefly explain?
One problem in studying tomato juice is that it has an opaque red color which would interfere with the observation of the color of a pH indicator.
Does each sample have measurable mass?
The answer depends on sample of WHAT!
What will be the sample size?
Number of Sample in set of observation.
What is an event sample observation?
it is an observation that looks closey at one aspect of a child's development.
What is the sample standard deviation of 27.5?
A single observation cannot have a sample standard deviation.
How much error is expected between the sample mean and population mean?
0. The expected value of the sample mean is the population mean, so the expected value of the difference is 0.
What group of subjects selected for observation in an empirical study?
sample
As the sample size increases what does the expected value of M do?
You have not defined M, but I will consider it is a statistic of the sample. For an random sample, the expected value of a statistic, will be a closer approximation to the parameter value of the population as the sample size increases. In more mathematical language, the measures of dispersion (standard deviation or variance) from the calculated statistic are expected to decrease as the sample size increases.

What is the expected shape of the distribution of the sample mean?
The distribution of the sample mean is bell-shaped or is a normal distribution.
What is the medical term meaning removing a sample of tissue for observation?
biopsy? excise/excision?
What happens to the expected value of M as sample size increases?
Decreases
The expected frequency is determined by multiplying the sample size by the hypothesized proportion?
True.
