For this task, assume that you have been asked to host a local forum for parents of junior high school aged children to discuss the consequences of having sex at an early age. Parents are debating the following topic: A sexuality education unit, at least a week in length, should be included in all grades in all schools. After the debate you are to draft a summary of the conversations. In your paper, provide both the pro and con of the debate. Provide examples for each side. Include what you would recommend be included and at what age or grade level it should be addressed.

You and your roommate live in a dorm room on campus. Your roommate has a friend who is on fall break at a different time than your school.

How will you work out this situation with her?

What conflict management style did you use?

What would you do if your roommate did not want to use this style?

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. It is estimated that 3.5% of the general population will live past their 90th birthday. In a graduating class of 781 high school seniors, find the following probabilities. (Round your answers to four decimal places.) (a) 15 or more will live beyond their 90th birthday (b) 30 or more will live beyond their 90th birthday (c) between 25 and 35 will live beyond their 90th birthday (d) more than 40 will live beyond their 90th birthday

Q. Consider a researcher interested in the causal effect of class size in primary school on educational attainments. The research strategies he is contemplating are (i) regression-control; (ii) randomization; (iii) difference-indifferences and (iv) regression-discontinuity. Explain the workings of each method along with the identification assumptions that enable causal inference. Discuss advantages and problems with each method.

Determine the Appropriate Analysis For each of the following scenarios, identify the appropriate analysis.

2. A guidance counselor at a high school wants to be best informed about the universities and colleges that students prefer most frequently. He glances at the institutions attended by last year’s graduates and notes that the three closet colleges appear to have about equal appeal. To test this assumption, he begins asking students who are planning on postsecondary schooling where they will apply. His data are as follows:

The technical institute: 22

The community college: 18

The comprehensive university: 12
