An article in the October 11, 2006, issue of the Washington Post claimed that 15% of high school students used cursive writing on the essay portion of the SAT exam in the academic year 2005-2006 (Pressler, 2006). Suppose you take a random sample from those exams and see what proportion of the sample used cursive writing for the essay. Assume the sample size is 180 do the following:

• A -- Determine what π and N are.
• B -- Describe the sampling distribution.
• C -- Show that the CLT holds.
• D -- What does the CLT say about the sampling distribution?
• E -- What is the probability of obtaining a sample where more than half of the students wrote their essay in cursive?
• F -- What is the probability of obtaining a sample where between 10 and 25% wrote their essay in cursive?
• G -- What is the probability of obtaining a sample where less than 12% of the students wrote their essay in cursive?

1. Seven hundred and seventy-one distance learning students at Long Beach City College, located in Long Beach, California (part of the Los Angeles metropolitan area) responded to surveys in the 2010-11 academic year. Highlights of the summary report are listed in the table below:

1. What percent of the students surveyed do not have a computer at home?
2. About how many students in the survey live at least 16 miles from campus?
3. If the same survey were done at Great Basin College in Elko, Nevada, do you think the percentages would be the same? Why?

Given the following research topic, answer the question below: Are there differences in university GPA and persistence rates between who enrolled in first-year seminars compared to those who did not enroll in first-year seminars?

a. What is the dependent variable(s)?

b. Are there any other dependent variables that might be of interest in this study?

c. What is the independent variable? Identify levels of the variable.

d. Why is this an example of ex post facto research?

e. Consider the extraneous variable high school (HS) GPA. Describe how you could control this extraneous variable through ANCOVA.

f. Consider the extraneous variable academic major. Describe how you could control this extraneous variable through homogeneous grouping.

g. Consider the extraneous variable campus living arrangement. Describe how you could control this extraneous variable through homogeneous grouping.

h. Suggest one additional extraneous variable and one way to control it.

1. What is the difference between legal and equitable remedies?
A buyer contracts to buy a 1941 four-door Cadillac convertible from a seller for $75,000. The seller, having found a third party who will pay $85,000 for the car, refuses to sell to the buyer. What is the buyer’s remedy? Assume the third party had paid the $85,000 and the seller was ordered to sell to the buyer. What is the third party’s remedy?
Professor Smith contracts to teach business law at State University for the academic year. After the first term is over, she quits. Can State University get an order of specific performance or an injunction requiring Professor Smith to return for the second term? Now suppose that the reason Professor Smith quit work at State University is because she got a better job at Central University, fifteen miles away. Can State University get an injunction prohibiting her from teaching at Central University?

Liquid penetrant testing is a suitable method for almost any material. What can not be inspected by liquid penetrant testing method?

Explain why pre-cleaning is the most important step

Imagine a part that contains fatigue cracks which are detectable under no load using liquid penetrant technique. Would they still be detectable under tensile and compressive loads and why?

List the main human factors that affect the probability of detection in liquid penetrant testing.

What control measures should be considered in developer thickness layer?

List the advantages and disadvantages of the various developer types.

Additionally there are 10 marks given for organisation and presentation. You will be expected to show evidence of research and well balanced arguments supported by academic literature relevant to the problem (in addition to the learning package material). Note that that the marking scheme gives an indication of the expected length of each section. Explanations and descriptions should reflect this balance between sections and sub-sections.

A survey is divided into three parts:

Part 1 includes socioeconomic status (SES) information; parent’s education, employment status (currently employed yes or no), income level, and receiving free or reduced lunch at school.

In part 2, the questions are regarding the environment at home, time spent watching (playing video games) TV at home, having a TV in their rooms, computer available to do assignments at home, Internet access at home, etc.

part 3, includes questions related to the safety of the neighborhood environment: some examples include if the students walk to school, how safe they feel while walking to and from school, do you feel safe at school? Are there a lot of fights at school? etc.

The purpose of you collecting these data is to create a model that can help to predict academic achievement in high school students using some of these variables.

1. Question: How could you measure for multicollinearity? Explain how you could address the multicollinearity

Reading journal articles can be challenging for students, as they are often technical in nature. A high school that prides itself on preparing students for college wants to purchase journals that are written at a level accessible to students. The school librarian recruits four students with varying academic ability to read articles from four different journals and rate their readability from 1 (very difficult to read and understand) to 7 (very easy to read and understand). Some hypothetical data are shown in the table.

Table: Journal and Readability

a) Perform an F test at alpha level .05, using excel. Submit your workbook showing the results.

b) What is the conclusion in terms of the null hypothesis, reject or fail to reject? Explain why.
