Question

a group of students conducted a science fair experiment to find out how the amount of fertilizer used will affect the growth of radish plants. the experiment was done for 10 days. use the table to analyze the data of the growth of the radish plants measured after 10 days. which inference is supported by the data? plant group a b c fertilizer concentration 50% 100% 150% average plant height (mm) 465 550 476 giving radish plants too little or too much fertilizer will slow down plant growth. giving radish plants more fertilizer will increase plant growth. giving radish plants too little or too much fertilizer will not affect plant growth. giving radish plants less fertilizer will increase plant growth.

Explanation:

When comparing the average plant heights for different fertilizer concentrations, plants with 100% fertilizer concentration (B) have a higher average height (550 mm) than those with 50% (A - 465 mm) and 150% (C - 476 mm). This shows that giving too little (50%) or too much (150%) fertilizer compared to the manufacturer's 100% recommendation slows down plant growth.

Answer:

Giving radish plants too little or too much fertilizer will slow down plant growth.
