LIST I | LIST II | ||
A. | Weight is considered as quantity in base year in, | I. | Paasche's index number |
B. | Weight is considered as quantity in current year in, | II. | Fisher's index number |
C. | The index number which is called as ideal index number is, | III. | Marshall-Edgeworth's index number |
D. | Weight is taken as the average of the base year quantity and current year quantity in | IV. | Laspeyre's index number |
To determine the correct matches between List I and List II, let's analyze each statement:
Based on this analysis, the correct matches for the lists are as follows:
A. | IV. |
B. | I. |
C. | II. |
D. | III. |
The correct answer is: A-IV, B-I, C-II, D-III
Let the Mean and Variance of five observations $ x_i $, $ i = 1, 2, 3, 4, 5 $ be 5 and 10 respectively. If three observations are $ x_1 = 1, x_2 = 3, x_3 = a $ and $ x_4 = 7, x_5 = b $ with $ a>b $, then the Variance of the observations $ n + x_n $ for $ n = 1, 2, 3, 4, 5 $ is
Find the mean of the following distribution:
\[\begin{array}{|c|c|c|c|c|c|c|c|} \hline \textbf{Class-interval} & 11-13 & 13-15 & 15-17 & 17-19 & 19-21 & 21-23 & 23-25 \\ \hline \text{Frequency} & \text{7} & \text{6} & \text{9} & \text{13} & \text{20} & \text{5} & \text{4} \\ \hline \end{array}\]
