Match the following :
| Group - I | Group - II |
|---|---|
| a. Type II error | 1. \(P_{01} \times P_{10} = 1\) |
| b. Mean \(\gt\) Mode | 2. Probability of not rejecting \(H_{0}\) when it was not true |
| c. Population is homogenous | 3. Positively skewed distribution |
| d. Time Reversal Test | 4. Simple random sampling |
Codes : a b c d
Answer: A
The correct match is a-2, b-3, c-4, d-1. A Type II error is the probability of not rejecting the null hypothesis when it is not true, a mean greater than the mode shows a positively skewed distribution, a homogeneous population is the case for which simple random sampling is suited, and the time reversal test requires that the price index for the current year on the base year multiplied by the index for the base on the current year is equal to one. This is the first option. The other options give a Type II error or a skewed distribution the wrong description.
