Let's work through the questions based on the image you provided.

### a. How many plants of each variety were planted?

To determine how many plants were planted for each variety, we count the number of height values for each variety:

- **Variety A**: The number of height values is 10 (46, 46, 47, 48, 49, 49, 50, 6, 48, 49).
- **Variety B**: The number of height values is 8 (48, 46, 45, 47, 48, 49, 47, 48).

So:
- **10 plants** of Variety A were planted.
- **8 plants** of Variety B were planted.

### b. The mean height of the corn plants of variety A is 43.8 inches. Interpret the value of the mean in the situation.

The mean height of 43.8 inches for variety A represents the **average height** of the 10 corn plants of Variety A. This means that if all the plants had grown evenly, each plant's height would be approximately 43.8 inches. It's a central tendency measurement showing the overall height pattern of Variety A plants.

### Related Questions:
1. How do you calculate the mean height for a data set like this?
2. What does the variation in heights tell us about the growth of the plants?
3. How can we interpret the presence of an outlier, like the 6-inch height in Variety A?
4. Why is it important to look at both mean and individual values in data sets like these?
5. How can you visually represent this data using a bar graph or box plot?

#### Tip:
When calculating the mean, it's important to consider whether there are outliers, like the 6-inch height in Variety A, that might skew the average.

For a science project, a student plants seeds of 2 different varieties of corn plants. The table displays the heights, in inches, of each of the corn plants after 8 weeks. How many plants of each variety were planted? The mean height of the corn plants of variety A is 43.8 inches. Interpret the value of the mean in the situation.

In this problem, students are asked to count the number of plants for two varieties of corn and interpret the mean height for one of the varieties. The data involves calculating the mean and understanding central tendency in statistics. Suitable for students in Grades 6-8.
