A study of identity theft looked at how well consumers protect themselves from this increasingly prevalent crime. The behaviors of 63 college students were compared with the behaviors of 58 non students. One of the questions was "When asked to create a password, I have used either my mother's maiden name, or my pet's name, or my birth date, or the last four digits of my social security number, or a series of consecutive numbers." For the students, 24 agreed with this statement while 29 of the non students agreed.

(a) Display the data in a two-way table.

Perform the chi-square test. (Round your χ² to three decimal places and round your P-value to four decimal places.)

Summarize the results.

We can conclude at the 5% level that students and nonstudents differ in the response to this question.We cannot conclude at the 5% level that students and nonstudents differ in the response to this question.    

(b) Reanalyze the data using the methods for comparing two proportions that we studied in the previous chapter. Compare the results and verify that the chi-square statistic is the square of the z statistic. (Test students who agreed minus nonstudents who agreed. Round your z to two decimal places and round your P-value to four decimal places.)

(c) The students in this study were junior and senior college students from two sections of a course in Internet marketing at a large northeastern university. The nonstudents were a group of individuals who were recruited to attend commercial focus groups on the West Coast conducted by a lifestyle marketing organization. Discuss how the method of selecting the subjects in this study relates to the conclusions that can be drawn from it.

A competing commercial effort to sequence the human genome was initiated by the company Celera in 1997. How was their approach different from the Human Genome Project?

• A. Libraries of individual chromosomes were generated and overlapping clones were isolated before sequencing.
• B. They used sequence tagged sites (STS) and expression sequence tags (EST) to order contigs prior to sequencing.
• C. They sequenced the entire genome from one female donor.
• D. They generated overlapping clones from YAC and BAC libraries that were identified by hybridization and organized into long contiguous stretches called contigs.
• E. They used a whole-genome shotgun sequencing method that eliminates the step of assembling a physical map of the genome.
