(a) Find the least-squares regression line treating the commute time, x, as the explanatory variable and the index score, y, as the response variable.
y = [ ] x + [ ]
(b) Interpret the slope and y-intercept, if appropriate. Interpret the slope. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. For a commute time of zero minutes, the index score is predicted to be [ ]
B. For every unit increase in index score, the commute time falls by [ ] on average
C. For an index score of zero, the commute time is predicted to be [ ] minutes
D. For every unit increase in commute time, the index score falls by [ ] on average
E. It is not appropriate to interpret the slope
Interpret the y-intercept. Select the correct choice below and, if necessary, fill in the answer box to complete your choice
A. For an index score of zero, the commute time is predicted to be
[ ] minutes
B. For every unit increase in commute time, the index score falls by [ ] on average
C.For every unit increase in index score, the commute time falls by [ ] on average
D. For a commute time of zero minutes, the index score is predicted to be [ ]
E. It is not appropriate to interpret the y-intercept.

Consider giving one dollar to a poor person, keeping in mind that among a country’s poor people, some have much lower incomes than others. Consider each of the aggregate poverty measures defined in the text, and assume that per capita household income is the measure of individual-level well-being they summarize. For each measure, discuss how the impact on the measure would differ depending on whether the additional dollar were given to a person who is just barely poor (with income just below the poverty line) or to a person who is very poor: (i) the headcount ratio; (ii) the total income gap; (iii) the average proportional income gap; (iv) the poverty gap index; (v) the P2 measure

22.A gene will increase in a population, even if it causes an individual's fitness to be immediately decreased, if:
|
the individual allows itself to be eaten. |
||
|
the individual acquires more relatives. |
||
|
that individual can gather more food. |
||
|
the individual fails to get reciprocity from others. |
||
|
an individual's "sacrificial" behavior leads to reciprocity and an overall fitness increase for that individual. |
23.Under what circumstances does reciprocal altruism appear in unrelated individuals?
|
When there are repeated interactions with opportunities for all individuals to be the donor and recipient of the altruistic act. |
||
|
When one individual gives up something of high value in exchange for frequent low-value returns in the future. |
||
|
Reciprocal altruism only appears when there are frequent interactions between close kin, and the outcome is an increase in relative fitness. |
||
|
When the benefits to the donor are significantly greater than the costs to the recipient. |
||
|
When there is anonymity among individuals in a population, so no one individual can be singled out and recognized. |

Why do babies in the United States easily develop a fear of snakes but not a fear of guns?
|
There is no known reason for this phenomenon. |
||
|
Babies are more likely to encounter snakes than guns as they develop in the United States |
||
|
Humans cannot develop fear toward inanimate objects. |
||
|
Fewer individuals are killed by guns than by snakes in the United States each year. |
||
|
Fear of snakes evolved in early humans with different living conditions, and evolution can be slow in producing populations that are adapted to their newer environments. |
