Question

use the information in the data table below in order to create a proper scientific graph and to answer the corresponding questions. water temperature (°c) 15 20 25 30 35 40 45 50 number of developing clams 72 92 120 140 99 72 36 0 1. what is the dependent variable? 2. what is the independent variable? 3. what is the optimum temperature for clam development? 4. what is the mean number of clams per sample? 5. approximately how many clams would be developing in 10 degree celsius water? 6. what predictions can we make as the prediction we made about data not yet recorded, such as developing in 10 degree celsius water? what is it called when you make predictions about data not yet recorded, such as developing in 10 degree celsius water?

Explanation:

Step1: Identify variables

Independent: Water Temperature; Dependent: Number of Developing Clams

Step2: Find optimum

From data, around 35 - 40 degrees Celsius seems optimum.

Step3: Calculate mean

Sum of clams: 72+92+120+140+99+72+36+0 = 631. Mean: $\frac{631}{8}=78.875$

Step4: Prediction

Insufficient data for accurate prediction at 10 degrees Celsius.

Answer:

1. Dependent: Number of Developing Clams
2. Independent: Water Temperature
3. Optimum: Around 35 - 40°C
4. Mean: 78.875
5. Can't predict accurately
6. Prediction number: N/A
