For a frequency distribution the coefficient of skewness based upon the quartiles is 0.6. If the sum of the upper and lower quartiles is 100 and median is 38, What is the value of lower and upper quartiles :

Which of the following factors are responsible for the E-size of the sample in sampling schemes ?
(1) Precision of the estimates required is an important factor in determining the size of a sample
(2) For greater precision, usually a larger sample is preferred
(3) For greater precision usually a smaller sample is preferred
(4) More is the heterogeneity, a larger is the size of the sample.
