Question

1. look at the chart. then, choose the best answer. pesticide experiment field pesticide number of dead insects after two weeks number of dead plants after two weeks control field 1 no 42 11 control field 2 no 22 21 control field 3 no 28 19 experimental field 4 yes 436 19 experimental field 5 yes 350 22 experimental field 6 yes 417 12 what is the best conclusion or reasoning of the data from the experiment? the pesticide spray kills more plants without killing insects. the pesticide spray kills more insects without killing plants. the pesticide spray has no effect on insects or plants. the pesticide spray kills more insects and plants. the pesticide spray kills fewer insects and plants.

Explanation:

Step1: Analyze insect - death data

In control fields (no pesticide), the number of dead insects is 42, 22, 28. In experimental fields (with pesticide), the number of dead insects is 436, 350, 417. Clearly, the number of dead insects is much higher in experimental fields.

Step2: Analyze plant - death data

In control fields, the number of dead plants is 11, 21, 19. In experimental fields, the number of dead plants is 19, 22, 12. The number of dead plants in experimental fields is not significantly different from that in control fields.

Answer:

The pesticide spray kills more insects without killing plants.
