Answer

Here is the frequency table for the candy guesses: - 1100–1199: 5 - 1200–1299: 4 - 1300–1399: 6 - 1400–1499: 1

Solution

We are given 16 guesses: 1138, 1147, 1278, 1142, 1286, 1328, 1327, 1384, 1258, 1177, 1361, 1121, 1411, 1215, 1328, 1349. A common way to classify these numbers is by using class intervals that cover the range of the data. Here, we can use the following classes:  • 1100–1199  • 1200–1299  • 1300–1399  • 1400–1499 Now, let’s tally the frequencies for each class: 1. 1100–1199:  - 1138, 1147, 1142, 1177, 1121  - Frequency = 5 2. 1200–1299:  - 1278, 1286, 1258, 1215  - Frequency = 4 3. 1300–1399:  - 1328, 1327, 1384, 1361, 1328, 1349  - Frequency = 6 4. 1400–1499:  - 1411  - Frequency = 1 Thus, the completed frequency table is:  Class  Frequency  1100–1199 5  1200–1299 4  1300–1399 6  1400–1499 1

Bonus Knowledge

To complete the frequency table, let’s first categorize the given guesses into classes. For example, we could use the following classes: - 1100-1199 - 1200-1299 - 1300-1399 - 1400-1499 Now, let's count the frequency of guesses within each class. - For the class **1100-1199**: 1138, 1147, 1142, 1177, 1121 → Frequency: 5 - For the class **1200-1299**: 1278, 1286, 1258, 1215 → Frequency: 4 - For the class **1300-1399**: 1328, 1327, 1384, 1361, 1349, 1328 → Frequency: 6 - For the class **1400-1499**: 1411 → Frequency: 1 The completed frequency table will look like this: | Class | Frequency | |-----------|-----------| | 1100-1199 | 5 | | 1200-1299 | 4 | | 1300-1399 | 6 | | 1400-1499 | 1 |
