Name: October 8, 2010 Friday T.A. name/Class time: Xiang Han Monday/Wednesday lecturer: Ellen Gundlach Lab 6: Chapter 6 and Section 7.1 Do poets die young? According to William Butler Yeats, “She is the Gaelic muse, for she gives inspiration to those she persecutes. The Gaelic poets die young, for she is restless, and will not let them remain long on earth.” One study designed to investigate this issue examined the age at death for writers from different cultures and genders. The ages at death for female poets from North America are given in the SPSS data file “age.sav”. Most of the writers are from the United States, but Canadian and Mexican writers are also included. We will assume that these poets represent a simple random sample of poets from the population. 1.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
