Understanding the Mode Calculation
The mode of a set of observations is the value that occurs most frequently. To find the mode, we need to count how many times each number appears in the dataset and identify the number with the highest count.
Identifying Observations and Frequencies
The given observations are:
35, 32, 28, 27, 25, 32, 31, 27, 32, 30, 32, 27, 31, 34, 32, 22
Let's list the frequency of each unique observation:
| Observation | Frequency |
|---|---|
| 22 | 1 |
| 25 | 1 |
| 27 | 3 |
| 28 | 1 |
| 30 | 1 |
| 31 | 2 |
| 32 | 5 |
| 34 | 1 |
| 35 | 1 |
Determining the Mode
By examining the frequencies, we can see that the observation 32 appears 5 times, which is more than any other observation in the list.
Therefore, the mode of the given observations is 32.

According to government data, 24 percent of teenagers in India under the age of 18 years live in households with incomes that are classified at a particular income level. A simple random sample of 400 teenagers in India under the age of 18 years was selected for a study of learning. If the government data is correct, which of the following best approximates the probability that at least 27 per cent of the teenagers in the sample live in households that are classified at a particular income level?
Which index satisfies the factor reversal test?
