1. The law of statistics, which says "Moderately large number of items chosen at random from a large group possess the characteristics of the large group", is referred to as
2. The difference between sample statistic and its corresponding population parameter is
3. Assertion (A): If regression coefficient of X on Y is greater than one, regression coefficient of Y on X must be less than one.
Reason (R): The geometric mean between two regression coefficients is the coefficient of correlation.
Reason (R): The geometric mean between two regression coefficients is the coefficient of correlation.
4. If in Binomial distribution mean is 10 and standard deviation 2, q will be
5. Consider the following statements:
1. Quartile deviations is more instructive range as it discards the dispersion of extreme items
2. Coefficient of quartile deviaton cannot be used to compare the degree of variations in different distributions
3. There are 10 deciles for a series
Which one of the above statements is/are correct?

2. Coefficient of quartile deviaton cannot be used to compare the degree of variations in different distributions
3. There are 10 deciles for a series
Which one of the above statements is/are correct?
6. Assertion (A): A reasonably sized sample drawn randomly from large sized population contains almost all the characteristics which exist in the population.
Reason (R): The theory of sampling is based on the two important laws of statistics, viz law of statistical regularity and law of inertia of large numbers.
