Question

Silkworms are raised commercially for the silk cocoons that they produce. In ten different trials, Jami's class raised silkworms under different temperatures to see what conditions are best for silkworm caterpillars in their first three instars or stages. In each trial, they began with 30 silkworm eggs. The table below shows the data Jami recorded.

Trial Number Temperature (°F) Number Surviving to Adulthood
1 55 0
2 60 1
3 65 1
4 70 3
5 75 6
6 80 12
7 85 26
8 90 19
9 95 7
10 100 0
