Task: Distributing Students into Groups and Counting Total Students in Last Two Groups

To solve this task, we need to distribute the given set of student heights into six groups with equal intervals and determine the total number of students in the last two groups.

Let's break down the steps to solve this task:

1. Given Data: The heights of the students are provided as follows: 157, 170, 182, 190, 165, 170, 171, 172, 174, 180, 192, 167, 179, 172, 164, 171, 176, 179.

2. Distributing Students into Groups: We need to distribute the students into six groups with equal intervals. To do this, we can calculate the range of the heights and divide it by the number of groups. Then, we can assign each student to the appropriate group based on their height.

3. Calculating the Range: To calculate the range, we subtract the minimum height from the maximum height. In this case, the minimum height is 157 and the maximum height is 192. Therefore, the range is 192 - 157 = 35.

4. Calculating the Interval: To calculate the interval, we divide the range by the number of groups. In this case, the number of groups is six. Therefore, the interval is 35 / 6 ≈ 5.83.

5. Assigning Students to Groups: We can assign each student to the appropriate group based on their height. We start with the minimum height and add the interval to determine the upper limit of each group. Students whose heights fall within a particular range are assigned to that group.

6. Counting Total Students in Last Two Groups: Finally, we need to determine the total number of students in the last two groups. To do this, we count the number of students in the fifth and sixth groups.

Let's calculate the groups and the total number of students in the last two groups:

- Group 1: Heights 157, 162, 167 - Group 2: Heights 172, 177, 182 - Group 3: Heights 187, 192 - Group 4: No students - Group 5: No students - Group 6: No students

Therefore, the total number of students in the fifth and sixth groups is 0.

Answer:

Based on the given heights of the students, we have distributed them into six groups with equal intervals. However, there are no students in the fifth and sixth groups. Therefore, the total number of students in the last two groups is 0.
