what is the blocking variable?
There is an interrelationship between four variables. There is a growth forest that has mice, owls and humans. The humans clear the forest for living area and decrease the amount of forest for the animals. When that occurs the mice need space and go into the building the humans built. On the mice is a flea that will cause a deadly virus to the humans. If the population of mice is kept below a certain level no person will get sick (because the mice will live in the forest) but if it goes above a level then people will get ill. The owls are unaffected by the flea. There are 620 acres of forest. Here are the variables:
I=number of cases of illness among the villagers
M=Mouse population
OP=owl population
A=Acres of trees remaining
I=.25M-20
M=1600-20*OP
OP=0.2A
Find the following:
What are the domain and range for each variable?
What is the maximum number of owls that can survive in the forest?
What is the maximum number of individuals that can become ill?
What does this tell us about…

As warm moist air rises, it begins to rotate around a low- pressure system. This rotation is sustained by warm ocean temperatures and a central low pressure. Once a sustained wind speed of 74 miles per hour is reached, the storm is considered a hurricane. As man-made climate change continues to increase the temperature of the Earth's oceans, it is expected that the strength of hurricanes will Typically, a lower central pressure within a hurricane's eye is associated with a higher wind speed. Here, statistical software (R/RStudio) will be used to explore this relationship by applying linear regression methods. Using a database of landfalling hurricanes in the United States, a linear regression will be used to correlate the central pressure of each hurricane to its maximum sustained wind speed. increase.

- A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables affected total help if he rejects the null hypothesis.
