Final answer:
A parameter of the 1000 dogs studied in Texas would be a characteristic measured using data from the entire population, such as the average weight of a specific breed or the number of dogs adopted from shelters.
Step-by-step explanation:
In the context of the 1000 dogs studied in Texas, a parameter of this population would be a characteristic that is calculated using data from all members of this population. For example, The average weight of a specific breed of dogs in the study can be a parameter because it is a numerical measure that characterizes the population.
On the other hand, The number of dogs adopted from shelters can also be a parameter if it represents data compiled from the entire population of 1000 dogs.
