6. The following paragraph is from USA TODAY, March 1992:

"I wonder whether we as a society fully understand and appreciate the subtext of the $650,000,000,000 we spend for health care? For example, how widely is it understood that total health care expenditures have risen 30\% faster than the GNP since 1970 while health care prices have increased 60% more rapidly than general price inflation? Is it fully appreciated that, despite this growth in the total amount of services, the even faster rise in their costs, and the $2,600 per capita we now are spending, access to basic health care services remains severely restricted for much of the population?''

Your question to be considered is do male and female NIU students respond differently to the question of whether every American high school graduate should be able to complete a college degree. Determine to use the chi-square statistic to test the null hypothesis that there is no significant difference between male and female NIU students in response to Q: "Do you think every American high school graduate should be able to complete a college degree?''

Proceed as follows:

1. Determine the level of significance you (your team) will use for the test.

2. Determine how your team will obtain a good sample of 80-100 NIU students to be polled.

3. Conduct the poll of the sample asking the question Q and allowing the responses "Yes'', "No'', "No opinion''. Tabulate responses.

4. Determine the expected distribution for responses to Q assuming the null hypothesis and the responses "Yes'', "No'', "No opinion''.

5. Determine the number of degrees of freedom for the chi-square test of the null hypothesis and the value of the x2 statistic which would cause rejection of the null hypothesis.

6. Compute the x2 statistic for the data obtained and tell if the null hypothesis should be rejected.

7. Write up a short report on your study including a description of the points carried on in #1-6 and a brief paragraph discussing the findings of the study.

You are to do this project working with your team of 4 students, but each student in the team is to do his/her own write-up of it.

I. An analytic scoring scale for the evaluation of problem solving capacity (an adaptation of a scale in the booklet How to Evaluate Progress in Problem Solving by Randall Charles, Frank Lester, and Phares O'Daffer published in 1987 by the National Council of Teachers of Mathematics).

Stages of problem solving	Scoring scale
(from George Polya's How to Solve It)
A. Understanding the problem	0: Complete misunderstanding of the problem 1: Only part of the problem misunderstood or misinterpreted 2: Complete understanding of the problem
B. Devising a plan to solve the problem	0: No attempt, or totally inappropriate plan 1: Partially correct plan based on part of the problem being interpreted correctly 2: Plan could have led to a correct solution if implemented properly
C: Carrying out the plan	0: No answer, or wrong answer based on an inappropriate plan 1: Copying error; computational error; partial answer for a problem with multiple answers 2: Correct answer and correct label for the answer.
D: Looking back at the solution	0: No answer or answer does not make sense in the context of the problem. 1: Answer makes sense even if not correct; solution is okay but could be better. 2: Solution is correct and a good one. Argument or result is checked in other ways when it can be. Interpretation appropriate and makes sense.

II. A scoring guide for judging the accomplishment of quantitative literacy goals.

A quantitatively literate college graduate should be able to:

1. Interpret mathematical models such as formulas, graphs, tables, and schematics, and draw inferences from them.

2. Represent mathematical information symbolically, visually, numerically, and verbally.

3. Use arithmetical, algebraic, geometric and statistical methods to solve problems.

4. Estimate and check answers to mathematical problems in order to determine reasonableness, identify alternatives, and select optimal results.

5. Recognize that mathematical and statistical methods have limits.

For each of the five capabilities listed above evaluate student attainment of that capability according to the following:

Score	Rating	Characteristics of student work
5	Excellent	Insightful understanding is effectively demonstrated. Whether directly stated or implied, responses are perceptive and appropriately supported by specific details. Support is well defined and appropriate.
4	Proficient	Well-considered understanding is appropriately demonstrated. Whether directly stated or implied, responses are thoughtful and supported by details. Support is well-defined and appropriate.
3	Satisfactory	A defensible understanding is clearly demonstrated. Whether directly stated or implied, responses are conventional but plausibly supported. Support is general but functional.
2	Limited	Understanding is vaguely demonstrated or is not always defensible or sustained. Responses are superficial and support is scant and/or vague, and/or redundant.
1	Poor	An implausible conjecture is suggested. Responses are irrelevant or incomprehensible. Support is inappropriate, inadequate, or absent.
0	Insufficient	The marker can discern no evidence for the capability. Responses are so deficient that it is not possible to assess the capability.

(Adapted from a guide for assessing writing assignments which appears in the book Assessing Student Performance by Grant P. Wiggins published in 1993 by Jossey-Bass Publishers.)

I. Social psychology---A foundations finite mathematics course is followed by a sophomore-level elementary statistics course. A junior-level research methods in psychology course which presupposes the finite mathematics course and the statistics course is taken. The research methods course is followed by at least one of three laboratory courses which are senior-level-- -clinical psychology laboratory, social and personality laboratory, and developmental psychology laboratory.

II. Music---A foundations quantitative literacy course is taken in the freshman year of studies. In each of the succeeding years, sophomore, junior, and senior, one course which has a substantial quantitative component is taken in fulfillment of the general education requirements---e.g., in the sophomore year principles and problems of microeconomics; in the junior year introductory geology; and in the senior year human nutrition.
