In desert river systems across the Southwestern states, dense stands of invasive tamarisk are displacing native tree species. These stands are often referred to as monocultures because tamarisk has become the numerically dominant species in these communities. Assuming that species richness (the number of species) is equal, use the following to calculate the Shannon- Weaver Index for each community.
Native Dominated:
Species 1 Species 2 Species 3
P, 0.3 0.4 0.3
PilnP -0.36 -0.37 -0.36
Tamarisk Dominated:
Species 1 Species 2 Species 3
P, 0.8 0.1 0.1
PilnP -0.18 -0.23 -0.23
Question: Calculate the Shannon-Weaver Index, H, for the Native Dominated community.
a. 0.64
b. 1.37
c. 1.09
d. 1.64

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
