## Data on Sitophilus orizae

### Description

s.oryzae is a list of three elements:

$data: 97 measures (in micrometers) of the headcapsule width of rice weevil larvae (*Sitophilus orizae*) belonging to any of four possible instars.

$mu4: the mean headcapsule width (in micrometers) estimated from 40 fourth-instar *S. oryzae* larvae.
These 40 larvae doesn't belong to the data set s.oryzae$data as stated previously.

$sd4: the standard deviation of headcapsule width (in micrometers) estimated from 40 fourth-instar *S. oryzae* larvae.
These 40 larvae doesn't belong to the data set s.oryzae$data as stated previously.

### Usage

data(s.oryzae)

### Format

The format is a list of three elements:

$data: a vector of 97 numerical values

$mu4 : a single numerical value

$sd4 : a single numerical value
