Question 1: A school is considering two videos for a class. Students have been randomly assigned to 2 groups, and they all take the same written test after watching the video. The scores are summarized below:

Video 1: sample mean = 77, sample standard deviation = 6.3, sample size = 29
Video 2: sample mean = 78, sample standard deviation = 6.8, sample size = 28

Conduct an analysis to determine whether there is a difference in the test scores for the two videos. Provide the test statistics value for the analysis.

You plan to be a doting grandparent for your three adorable yet unborn tots (you love to plan ahead). You plan on setting up a trust fund to pay for their undergraduate educations. The fund will be set up to pay each little one $260,000 for the first year of school, then increase at 4% per year through graduation. Assume the grandkids graduate after 4 years. The oldest tot begins school in 35 years; the second one starts three years later and the last little one starts two years after the second. You have set aside $100,000 thus far. You earn 6% on your investments. Next year’s salary is expected to be $180,000. What fraction of your salary must you set aside if you get raises of 2% per year to make your vision a reality? You start your savings based on income one year from now and you make your last payment on the first grandchild’s first day at college.

Question Workspace Check My Work Steven was often bullied in his school. He was shy and somewhat reclusive, and sometimes the object of peer comment and jokes. Jason, a senior and also the biggest of the school bullies, was also in Steven’s classes. After long periods of this happening, Steven developed a grave dislike for Jason. Jason, as one of his projects for computer science class, developed his own personal Web site, and started promoting it to showcase his Web development skills. To impress his friends, he passed out the IP address of his site, so they could comment on it.

In the meantime, Steven, alone, as was his norm, came across several articles on hacking, and was fascinated by articles on scanning tools. He decided to download some of the tools and try them on Jason’s marvelous Web site.

a). What kinds of information would Steven discover using these scanning tools?

b). Will his scanning activities have any affect on Jason’s Web site?

c). Is what Steven is doing legal or ethical, and could he get into trouble for it?

A sociologist researching the link between race and inequality believes that younger people and/or people with more education generally have more tolerant views. To test this hypothesis, the sociologist gathers a random sample of 10 Caucasians ranging in age from teenager to elderly and asks them for their beliefs about African-Americans on a 10-point scale (1 representing acceptance of negative beliefs, 10 representing acceptance of positive beliefs), and number of completed years in school (including college if applicable). Check to see if his idea about the relationship between age and racial stereotyping and education is correct by conducting the correct comparative analysis and interpreting the results in context with APA notation in your response and an APA style table depicting the results.

John and Daphne are saving for their daughter Ellen's college education. Ellen just turned 10 at (t = 0), and she will be entering college 8 years from now (at t = 8). College tuition and expenses at State U. are currently $14,500 a year, but they are expected to increase at a rate of 3.5% a year. Ellen should graduate in 4 years--if she takes longer or wants to go to graduate school, she will be on her own. Tuition and other costs will be due at the beginning of each school year (at t = 8, 9, 10, and 11). So far, John and Daphne have accumulated $15,000 in their college savings account (at t = 0). Their long-run financial plan is to add an additional $5,000 in each of the next 4 years (at t = 1, 2, 3, and 4). Then they plan to make 3 equal annual contributions in each of the following years, t = 5, 6, and 7. They expect their investment account to earn 9%. How large must the annual payments at t = 5, 6, and 7 be to cover Ellen's anticipated college costs?   

A survey was conducted to study if parental smoking is associated with the incidence of smoking in children when they reach high school. Randomly chosen high school students were asked whether they smoked and whether at least one of their parents smoked.

The results are summarized in the following table:

Student Smoke Student Don’t

Parents Smoke 262 183

Parents Don’t 120 380

(a) For a randomly selected student in this study, find the conditional probability of smoking given his/her parents smoke.

(b) Suppose we are interested in testing whether parental smoking is independent of children smoking. Which statistical test would you consider for this problem?

(c) (4 points) Write down the R code to carry out that test. You first need to store the data into a matrix.

(d) Calculate the test statistic by yourself.

(e) Write down the R code to obtain the p-value based on your answer in
part(d).
(f) Suppose the p-value is 0.0001, what would be your really world conclusion? (You may use α = 0:05.)

Q1.During class we discussed some of Durkheim’s findings; here is your chance to apply those ideas to a current situation. The Federal Government released the following data in late 2016: “The suicide rate among U.S. middle school students (defined as between 10-14 years old – tom’s note) doubled from 2007 to 2014, surpassing for the first time the incidence of youngsters aged 10 to 14 who died in car crashes … Those figures contrast sharply with figures from 1999, when the rate of middle school students killed in car crashes, was four times higher than the rate among those who died from suicide that year.” A researcher involved in analyzing the data stated: “In time we might uncover somFor this question, you are to become Durkheim and explain why we see each of these results. Remember to focus on the idea of social bonds. Which of Durkheim’s 4 types of suicide is represented by this data? Explain your choices.e reasons…”

A Recent Graduate’s Debt Status

Chelsea Menken, of Providence, Rhode Island, recently graduated with a degree in food science and now works for a major consumer foods company earning $70,000 per year with about $57,600 in take-home pay. She rents an apartment for $1,100 per month. While in school, she accumulated about $38,000 in student loan debt on which she pays $385 per month. During her last fall semester in school, she had an internship in a city about 100 miles from her campus. She used her credit card for her extra expenses and has a current debt on the account of $7,000. She has been making the minimum payments on the account of about $240 a month. She has assets of $14,000.

Missy, age 30, has owned her principal residence (adjusted basis of $225,000) for five years. During the first three years of ownership, she occupied it as her principal residence. During the past two years, she was in graduate school and rented the residence. After graduate school, Missy returned to the same location where she previously worked. At this point, she purchased another residence for $400,000 and listed her old residence for sale at $340,000. Due to a slow real estate market, 11 months later Missy finally receives an offer of $330,000.

1. What is Missy’s recognized gain if she immediately accepts the $330,000 offer (i.e., 11 months after the listing date)? Selling expenses are $20,000.
2. What is Missy’s recognized gain if she rejects the $330,000 offer and accepts another offer of $340,000 three months later (i.e., 14 months after the listing date)?
3. Advise Missy on which offer she should accept (assume that she is in the 24% tax bracket).
