question 41

Essay

As part of the iguana risk assessment experiment described in the previous problem, investigators replicated the experiment with one difference--the investigators approached the iguanas at a tangent, passing by the iguana with a closest distance being 2 meters. Summary statistics for the approach distances for the two treatments, Eye Contact and No Eye Contact, are given in the table below: An initial analysis of the data revealed that it was reasonable to assume the population approach distances at first run were both approximately normal.
a) Construct a 95% confidence interval for the difference in approach distances for the eye contact and no eye contact treatments.
b) Do the data indicate that for a tangential approach, the population means differ? Justify your answer statistically.
