1. Problem Description

The problem provides a data set of the number of hours of sleep eight staff members got on Thanksgiving night. The data is presented in a 2×42 \times 4 table. We need to create a frequency table that shows the number of employees who got 6, 7, and 8 hours of sleep.

2. Solution Steps

First, let's list the data set: 6, 7, 8, 7, 7, 8, 7,

6. Next, we count how many times each number appears in the dataset.

- The number 6 appears 2 times.
- The number 7 appears 4 times.
- The number 8 appears 2 times.
Therefore, the frequency table entries are:
- 6 hours of sleep: 2 employees
- 7 hours of sleep: 4 employees
- 8 hours of sleep: 2 employees

3. Final Answer

Number of employees who got 6 hours of sleep: 2
Number of employees who got 7 hours of sleep: 4
Number of employees who got 8 hours of sleep: 2
