Although traffic fatalities have been decreasing for years, this decrease has not been experienced equally in all segments of the population. In fact, although the overall rate of traffic fatalities has been decreasing, the rate has declined the most for those with more education and has actually gone up for those without high school degrees. A recent study shows that among those over 25, as education level increased from less than high school, to high school grad, to some college, to college grad, the rate of motor vehicle crash deaths decreased.
1) What are the explanatory and response variables? Drag each variable to the appropriate column
1. Rate of motor vehicle crash deaths
2. Level of education
A) Response Variable
B) Explanatory Variable
2) Those with less education tend to drive cars that are older, have poorer crash test ratings, and have fewer safety features such as side airbags. Are the variables age of car, crash test rating, and presence of safety features explanatory variables, response variables, or lurking variables?
A) They are all explanatory variables since they are all characteristics of a car.
B) They are lurking variables as they are neither the primary explanatory nor response variables
C) They are all response variables since they can determine how much damage a car will receive in a motor vehicle crash.
D) None of the choices are correct education level good.
3) Is the association between traffic fatalities reason to think that a higher level of education actually causes an individual to be a safe driver? None of the choices are correct
A) Without an experiment, no causal relationship can be made.
B) There is a causal relationship because the study shows that the level of education has an impact on traffic fatalities are associated.
C) There is a causal relationship because level of education and motor vehicles.
D) None of the choices are correct.

Answer:

1.

The explanatory variable is the level of education.

response variable is Rate of motor vehicle crash deaths

2. b

3. A) Without an experiment, no causal relationship can be made.

Step-by-step explanation:

1.

The explanatory variable is the level of education.

The explanatory variable tells us that more education among people over 25 years, brings about a reduction in motor deaths.

The response variable is the rate of motor vehicle deaths.

This variable actually responds to the changes in the explanatory variable. The rate of motor vehicle deaths could increase or decrease based on the level of education.

2.

They are lurking variables. option B

These variables are not known primarily as explanatory variables here in this relationship but they have the ability to affect the result of the study.

3. We have to carry out an experiment first in order to carry out a causal relationship.

An automobile dealer can sell 12 cars per day at a price of $17,000. He estimates that for each $300 price reduction he can
sell two more cars per day. If each car costs him $14,000, and fixed costs are $1000, what price should he charge to
maximize his profit? [Hint: Let x = the number of $300 price reductions.]
How many cars will he sell at this price?

Bethany is a biologist who has been measuring and recording the rabbit population at a park over the last several years. She has noticed that a trigonometric function can model the population, which reaches a maximum population, m, each summer and a minimum population, n, each winter. If she uses to represent the rabbit population t years from the start of her study, what is the domain of function p?
