Before entering the course the student should be able to:

  1. demonstrate a working knowledge of the Cartesian coordinate system including: slope of a line, equation of a line, delta notation;
  2. demonstrate an understanding of the nature of a function;
  3. graph algebraic and trigonometric functions;
  4. explain limits and continuity of functions;
  5. use Newton's method;
  6. apply the definition of the derivative of a function;
  7. demonstrate the knowledge of the definitions of velocity and acceleration;
  8. differentiate algebraic and trigonometric functions;
  9. use the chain rule;
  10. find all maxima, minima and points of inflection on an interval;
  11. apply implicit differention to solve related rate problems;

  14. demonstrate the knowledge of the fundamental Theorem of Integral Calculus;
  15. demonstrate the understanding of differentials and their applications.

Expected Outcomes for Students:

Upon completion of the course the student should be able to:

  1. take raw data and compile a frequency table from which frequency histograms and relative frequency histograms can be drawn;
  2. calculate the mean, median, mode, variance and standard deviation of a distribution;
  3. demonstrate the fundamental concepts of probability and be able to calculate probabilities of various independent and dependent events;
  4. demonstrate the knowledge of the nature of the binomial distribution and the normal distribution, as well as properties of the normal probability curve;
  5. use tables of standard z values and student's t distribution;
  6. describe the differences betweens samples and populations, sampling methods, and experimental designs;
  7. calculate confidence intervals and tests of significance for one and two samples;
  8. demonstrate the procedure and uses of correlation and regression;
  9. demonstrate the use of computer software packages as they pertain to histograms, regression analysis, confidence intervals, and hypothesis tests;
  10. explain the nature of the chi-square distribution and its use for goodness of fit and independence tests.

Assignments and Methods of Evaluating Student Progress:

1.Typical Assignments

  1. Exercises from the textbook
  1. Grandma's Jam Company, is a maker of premium preserves, and very few of its

16oz jars should to contain less than 16 oz of product. Management decides that

16.1 oz (on the average) will be put in the jars so that very few will be

underweight.

Listed below are the weights of 25 jars (one chosen every 15 min) filled by one

machine during one day's shift. The data are in order by row. [Data is given.]

  1. Construct a run chart and determine whether the process is statistically stable.
  2. Construct a boxplot of the weights.
  3. Construct a histogram of the weights. Does the process appear to result in values with a bell-shaped distribution?
  1. Computer projects
  1. Suppose you want to predict the amount of nicotine in a cigarette based on the

amount of carbon monoxide using Data Set 8. Determine whether a regression

analysis is appropriate in this case. If it is, perform a complete regression analysis

2. Methods of Evaluating Student Progress

a. Quizzes

b. Tests, including a final exam

c. Computer projects
