Researchers have found that a significant proportion of women, particularly women in heterosexual relationships, fake or have faked orgasm. Based on what we've read this quarter (that means, do your best to try to be sociologically analytical), why do you think women sometimes fake orgasm? What does it have to do with gender roles and/or expectations? What does it have to do with messages girls and women learn about sexuality? And finally, who "benefits" from women faking orgasms, and who is "harmed?" To do well on this question, you should refer to this week's readings, as well as course material about gender roles from earlier in the quarter.

1. The Back Street Girls Corporation has two different bonds currently outstanding. Bond M has a face value of GH¢20,000 and matures in 20 years. The bond makes no payments for the first six years, then pays GH¢1,000 every six months over the subsequent eight years, and finally pays GH¢1,750 every six months over the last six years. Bond N also has a face value of GH¢20,000 and a maturity of 20 years; it makes no coupon payments over the life of the bond. If the required return on both these bonds is 14 percent compounded semiannually, what is the current price of Bond M? Of Bond N?

I believe that the population proportion of Elementary students in Texas who ride the bus to school is more than the population proportion of Elementary students in Oklahoma. In two independent polls I found that 659 of 3502 students ride the bus in Texas and 476 of 3201 students in Oklahoma ride the bus to school. Assume a random sample. Calculate a 90% confidence interval of the two proportions.
