Mice can be a serious public health issue, as they can carry disease and parasites. It is important to track their feeding and living spaces. The accompanying data are a subset of data from a scatterplot that appeared in the paper "Small Mammal Responses to Fine Woody Debris and Forest Fuel Reduction in Southwest Oregon."+ The authors of the paper were interested in how the distance a deer mouse will travel for food is related to the distance from the food to the nearest pile of fine woody debris. Distances were measured in meters. Distance from Debris in Meters (x) 6.94 m 5.23 5.21 7.10 8.16 5.50 9.19 9.05 9.36 Distance Traveled in Meters (y) 0.00 6.13 11.29 14.35 12.03 22.72 20.11 26.16 30.65 The equation of the regression line is ŷ = -7.69 + 3.23x. How far (in m) would we predict a mouse to travel for food if the distance from a pile of debris is 7.49 m? (Round your answer to two decimal places.)

Your state is going to vote on becoming a "right to work" state in the next, and you wonder if there is there a relationship between salary levels and unionization. You find data on salary from the U.S. Census, which is split into three groups: Low; Moderate/About Average, and; High. To see if salary, measured in this way, is associated with unionization you find a variable in the same dataset called "UNION", which has two categories: the respondent has a unionized job and the respondent does not have a unionized job. Because you want to know if you should favor or oppose becoming a "right to work" state, you test these two variables to see if there is an association between salary level and unionized labor. What type of hypothesis test is most appropriate?

Answer only the requirement 2 and 3.

if a study determines the difference in average salary for subpopulations of people with blue eyes and people with brown eyes is not significant then the populations are blue-eyed people and brown-eyed people are what different salaries
