STAT2507A – Lab 6 – July 11, 2009 Introduction The National Longitudinal Survey of Children and Youth (NLSCY) is a unique study of  Canadians from birth to adulthood. The data file is a sample file based on the NLSCY data  containing 359 records. It represents 359 youth, approximately one fifth of the 16-17 year old  cohort who completed the survey in 2002-2003.  The respondents were asked a series of questions about themselves and their lives. The  questions were divided into the following seven categories: Section A: Friends and Family Section B: About Me Section C: Feelings and Behaviours Section D: Smoking, Drinking, and Drugs Section E: Health Section F: My Relationships Section G: My Parent(s) The questionnaire answered by the respondents is also available in the directory. (Note: for the purposes of this lab, we will assume that the 359 students represent a simple  random sample without replacement.  In reality, the sampling methodology is not simple random  sample.) Exercises 1 Produce an estimate for the average weight of 16-17 year olds in kilogram using the sample.

    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.
