Background:
Sexual selection can favor extreme versions of certain traits.
The good genes hypothesis proposes that females choose to mate with
males that have high survivorship. But how can the female measure
the male's survival skills? The good genes hypothesis proposes that
male secondary sexual characteristics advertise his genetic
quality. Extravagant ornamentation equals high survivorship.
Male barn swallows (Hirundo rustica) have longer tail feathers
than females and the length of male tail feathers varies in a
population. Anders Moller wanted...

24) Two groups of randomly selected drivers are surveyed to see how many miles per week they drive for pleasure trips. At alpha equal to 0.01, can it be concluded that single drivers do more driving for pleasure trips on average than married drivers? Assume the population standard deviation for single drivers to be 16.7 and the population standard deviation for married drivers to be 16.1. Test the hypothesis using the methods listed below. Single drivers 110 97 Married drivers...

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...
