The reason for that the comparison of particle size of different instrumental techniques to be always qualitative needs to be explained. Concept introduction: The size of particle is determined by using the different instrumental techniques and each instrumental technique required certain information. Some specific instrumental technique required specific data such asrefractive index or density and the availability of these data is not certain therefore; sometime information leads to discrepancies.

What are the advantages and disadvantages of using external standards in instrumental analysis?

The ages of a group of 122 randomly selected adult females have a standard deviation of 18.5 years Assume that the ages of female statistics students have less variation than ages of females in the general population, so let o = 18 5 years for the sample size caloulation How many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students? Assume that we want 95% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is (Round up to the nearest whole number as needed)
