Question

Find the mean number of beans eaten for each of the three-day periods: Days 1 to 3, Days 4 to 6, and Days 7 to 9. Use the values you recorded in Table D of your Student Guide.

Record the mean numbers in Table E.

Answer 1

To calculate the mean number of beans eaten for each three-day period, you will want to follow these steps:

1. **Sum the number of beans eaten for each three-day period.**
2. **Divide that sum by the number of days in the period (which is 3).**

### Example Calculation:

Suppose the data for the number of beans eaten on each day is as follows:

- **Day 1:** 10 beans
- **Day 2:** 15 beans
- **Day 3:** 20 beans
- **Day 4:** 25 beans
- **Day 5:** 30 beans
- **Day 6:** 35 beans
- **Day 7:** 40 beans
- **Day 8:** 45 beans
- **Day 9:** 50 beans

**Step 1: Calculate the Sums for Each Three-Day Period:**

- **Days 1 to 3:** \( 10 + 15 + 20 = 45 \)
- **Days 4 to 6:** \( 25 + 30 + 35 = 90 \)
- **Days 7 to 9:** \( 40 + 45 + 50 = 135 \)

**Step 2: Calculate the Means:**

- **Mean for Days 1 to 3:** \( \frac{45}{3} = 15 \)
- **Mean for Days 4 to 6:** \( \frac{90}{3} = 30 \)
- **Mean for Days 7 to 9:** \( \frac{135}{3} = 45 \)

### Final Results:
Now, you can record these means in Table E:

| Period | Mean Number of Beans Eaten |
|------------|-----------------------------|
| Days 1 to 3 | 15 |
| Days 4 to 6 | 30 |
| Days 7 to 9 | 45 |

If you have specific values from your Table D, please provide those numbers, and I can help calculate the means based on that data.
