SENATE ADDS SENATOR HUTCHISON'S SINGLE SEX EDUCATION AMENDMENT

*Legislation will provide funding for single sex education options in public
schools*

WASHINGTON, D.C. -- The U.S. Senate today unanimously approved an amendment
introduced by Senator Kay Bailey Hutchison to permit creativity grants to include
single sex education programs in public schools and classrooms.

"This legislation will give public schools the opportunity to provide the
same options now available in private and parochial schools. It will give more
choices to parents who believe that their children would do better in a single-sex
education environment," said Senator Hutchison.

"I want every child in this country to be given the chance to reach his
or her full potential," said Senator Hutchison. "If a child or parent
believes that there is a better chance of success in a single-sex classroom,
then public schools should have the ability to provide options to fit a child's
needs. This amendment will make those options possible."

Activity 1

## Purpose: To better understand what a confidence interval is.

## 1. Using the data from the survey, determine the proportion of students at USMA who indicated that they might like to attend a single sex school. This is a small sample of the students at USMA. What can you say about the beliefs of the entire student body at USMA? Calculate a 95% confidence interval for this data. Explain your results.

## 2. Run the following applet.

You need to enter a value for , theta, (population proportion), n (sample size), the number of intervals and the confidence level. Then, you click the recalculate button. ## Click here for the applet.

## 3. Explain what a confidence interval is using the green and red lines as part of your explanation.

## 4. Choose a variable from the survey that interests you. For each of the schools, calculate a 95% Confidence Interval for that variable.

## 5. Plot the confidence intervals on the same horizontal axis. What conclusions can you draw?

## Activity 2

Question: Is the school that you attend independent of the different views on Single Sex Education?

1. Decide on the methods that you will use to gather the information from the database.

Which report format should you select?

2. Download this information into your statistical software or graphing calculator.

3. Perform the appropriate analysis on the data. Justify the statistical test that you have chosen.

4. Write a paragraph to explain your results.

5. Repeat the above analysis on two different variables of your choice.

Activity 3

1. Construct side-by-side boxplots for the number of hours spent on schoolwork for each of the four schools.

Write a paragraph describing your impressions.

2. Repeat #1 for math SAT scores.

Activity 4

1. For each of the four schools determine how the number of hours spent on schoolwork is related to the math SAT scores.

Write an essay comparing and contrasting the four schools. Incorporate a complete analysis.

Be sure to explain all your work .

2. Now look at the data in aggregate. What changes do you see? What causes these changes?
