Ok I just need clarification on what Question 3 or 4 wants
Lab Assignment:
Working individually, download the auklet nesting data or gyrfalcon data from blackboard, or locate
a suitable data set of interest with about 200 data points (more is fine, some will be much, much
larger). The data should be ratio data (have a non-arbitrary zero value). Take 4 sets of samples
from this data set;
1) a simple random sample that is 10% of the total population of data (e. g.,
20 out of 200)
Mean: 155.6905
Standard Error:2.3457
2) a simple random that is 50% of the total population of the data
Mean: 155.8894
Standard Error:1.05406
3) a stratified sample that is 10% of the total population of data (uniform allocation)
4) a stratified sample that is 50% of the total population of data (again, with uniform allocation). You must decide
The strata used are the different locations where the chicks where in their nests:
cb: βCorm blindβ. West side of island, flat, little gull predation
cg: βCoast Guardβ. South side of island, flat, heavy gull predation
cs: βCarp Shopβ. East side of island, flat, moderate gull predation
lh: βLight Houseβ. South side of island, steep, moderate gull predation
ohh: βLight House Hillβ. South side of island, steep, moderate gull predation
