1.According to the website http://womenissues.about.com/cs/abortionstats/a/aaabortionstats.htm there are approximately 126,000 abortions conducted each day throughout the world. This website includes the abortion statistics of the world and breaks the data down to the demographics of the United States. It also discusses the decisions to have an abortion and the use of contraceptives in the United States. This was an informative website and included detailed statistics conducted by the Alan Guttmacher Institute. According to the website http://www.bls.gov/cps in 2000, gon average there were roughly 135 million employed and 6 million unemployed people in the labor force in the United States.h (p. 3) The websites definition of unemployed is: gpersons are classified as unemployed if they do not have a job, have actively looked for work in the prior four weeks, and are currently available for work.h (P. 2). These statistics were collected from unemployment insurance programs. The data was informative but probably not completely accurate since the numbers only included those individuals who participated in unemployment insurance programs. According to the website www.statistics.gov.uk gthe United Kingdom population is projected to increase by 7.2 million over the period of 2004 to 2031.h (p. 1). The growth rate is based on increased future birth rates and lower death rates. The website was informative, but since this is a future prediction, there is not much supporting documentation to support the statistic.

2.The website http://www.sfsu.edu/~acadplan/ugexits01-02.htm provides an undergraduate exit survey that has to be completed during the graduation application process for San Francisco State University. The survey will be categorized into various levels of data, demographic, attitudinal, nominal, ordinal, interval, and ratio. The level of data for the questions will be identified in bold and underlined wording.

Summary:
a) The mean sales per week surpasses 41.5 per salesperson. This is the right assumption. Statistical evidence is sufficient to back this claim with associated probability of committing an error which is called p-value = .022. The lower limit of the 95% confidence interval is 41.654. This implies that we can be 95% confident that the average (mean) sales per week exceeds 41.5 per salesperson since 41.654 > 41.5 and therefore our confidence interval...
