Question:
Velvetleaf is a particularly annoying weed in cornfields. It produces lots of seeds, and the seeds wait in the soil for years until conditions are right. Here are counts from 28 plants that came up in a cornfield when no herbicide was used:
2450 2504 2114 1110 2137 8015 1623 1531 2008 1716 721 863 1136 2819 1911 2101 1051 218 1711 164 2228 363 5973 1050 1961 1809 130 880
How many seeds do velvetleaf plants produce?
What is the range ?
Required Information:
mean number of seeds produced = ?
Range = ?
Answer:
mean = 1867.75
Range = 130 - 8015
Step-by-step explanation:
The mean number of seeds produced by velvetleaf plants is
mean = (2450+2504+2114+1110+2137+8015+1623+1531+2008+1716+721+863 1136+2819+1911+2101+1051+218+1711+164+2228+363+5973+1050+1961+1809+130+880)/28
mean = 52297/28
mean = 1867.75
To find the range of seeds first arrange the data in ascending order.
130 164 218 363 721 863 880 1050 1051 1110 1136 1531 1623 1711 1716 1809 1911 1961 2008 2101 2114 2137 2228 2450 2504 2819 5973 8015
Therefore, the range of the seeds is
130 to 8015
