Statistics EXAM - Speech or Presentation Example To test if a trend exists relating the GPA and the mother’s age at the birth of the child, regression analysis may be used. A simple linear regression is used in this particular calculation. The following table is set up from the raw data. It should be noted that the independent variable is the age at birth while the dependent is the GPA. Since 0.632, H0 cannot be rejected. There is insufficient evidence to support that a relationship exists between the mother’s age at the time of the child’s birth and the corresponding intelligence (as measured by GPA). The number of samples is determined based on the target error and confidence. Since no estimate of the proportion is given, a conservative value of 0.5 is to be used. The resulting calculations are shown as follows: Evaluating the scores of standardized examinations revolve largely around the normal distribution. From this particular problem, the SASS scores differ from the raw scores provided. In order to normalize the values the raw scores must be converted into z-scores and applied to the mean and standard deviation of the SASS. The equivalent z-scores for 151, 140, and 136 are computed below: Interpreting these scores as percentiles show that Robert, Ann and Carlos have percentiles at 90.32%, 77.34%, and 70.88% respectively. To normalize into the SASS standard scores, the z-scores are used with the mean and standard deviation standards. This is shown as follows: Assuming that no correlation exists between the high school GPA and the SASS score, the percentage of the applicants that are denied admission can be determined from the z-score equivalent of 60 on the SASS: From the z-score table, this corresponds to a cumulative probability of 0.7486 from the left. This means that 74.86% of the applicants have a SASS score below 60 and cannot be admitted into the university. This story is very much

How does the financial crisis affect the students 2. Background of the study America is currently in the midst of a tremendous economic crisis, with inflation reaching unprecedented and unanticipated levels. This has resulted in a tremendous rise in the cost of living which has made living a challenge to the general public and to the student population in particular as they have limited resources at their disposal. The students, those who are pursuing higher education in colleges and universities outside their home town in particular have to bear the costs of college fees, accommodation, living expenses and other courseware...In such a situation the rise in cost of essential items such as gasoline, electricity negatively impacts the quality of their studies. For the greater majority of students, borrowing money from banks has become a necessity to fund for their college and university education. On average, students in the US now graduate with at least $21,000 in debt and in some extreme circumstances students graduate with $100,000 in debt or more. Tuition fees at private colleges and universities have gone up tremendously - far ahead of inflation. Parents are losing jobs or their salaries are reduced as a result of the economic crisis. Thus the amount that parents can contribute towards their children's education is decreasing. This means that a greater number of students are dependent on loans for their college and university education. Every student who is currently attending or applying to college currently is horrified by what is going on in the financial markets. Things such as bonds for student loans are affected as a result. There will be a direct impact on student borrowings that will most likely be affected by the current financial crisis.
