Tikal National Park in Guatemala is heavily visited by tourists. Does the disturbance affect animal densities? To investigate, Hidinger (1996) compared the densities of various
bird and mammal species in places immediately next to heavily visited ruins to places in the park that were rarely visited by tourists. The mean densities (in animals/km^2)
are found in the accompanying table. The table also lists the P-value associated with a test of the null hypothesis that the two types of plots do not differ in mean density.
Assume that a = 0.05.
Name ONE species from that table that shows a significant increase in density near heavily visited ruins?
(yes or no) Is it a significant difference?
For the spider monkey, does it appear to be a higher mean density near ruins?
(yes or no)
The species column represent what type of data?
(nominal, ordinal, ratio or interval)
(nominal, ordinal, ratio or interval) Is it discrete or continuous?
Mean density represents what type of data?
(discrete
or continuous)
What kind of graph would be the best way to display this data?
(scatter plot, line graph, bar graph, histogram, heat map)
