Question

the graph below is the graph of a probability density function f(x) for the length of the larval stage, in days, for a certain breed of insect. Use the graph to answer the following questions.

What percentage of these insects is in the larval stage for between 8 and 12 days? What percentage of these insects is in the larval stage for less than 12 days? What percentage of these insects is in the larval stage for more than 14 days? In which one-day interval is the length of a larval stage most likely to fall?

Explanation / Answer

Total boxes =14

1) B/w 8-12 days 7.5 so 7.5/14=50%

2)9.5/14=67.85%

3)3/14=21.42%

4)10-12
